I love to exercise.
I know to some people this might seem foreign,
but I love to exercise.
I love to do resistance training, I love to run.
I am not one of those people
that doesn't like the experience of exercising,
but likes the feeling afterwards, quote unquote.
I hear that a lot.
"I don't like to exercise,
but I love the way I feel afterwards."
I love physical training,
and I love the way I feel afterwards,
but I mostly love the feeling during.
I don't know why I'm wired that way.
I can't say that I'm somebody
who likes to do hard things across the board.
There are plenty of difficult things in life that I dread
or that I'm sort of meh about,
but for me, hard exercise,
intense exercise of a particular kind.
Resistance training and running in particular,
both give me a yum.
Yes, I love this kind of feeling.
And yes, it persists for me quite a long while afterwards,
both for sake of the way that it changes my neurochemistry,
but also, my sense of satisfaction.
But I just simply love it.
Now, years ago, I discovered that
if I drink a cup of black coffee,
or an Americano or a double espresso, or some yerba mate,
that my workouts can be quite a bit more intense,
I can run further.
And then I also discovered that,
if I were to take a pre-workout energy drink,
or I took say 300 milligrams of Alpha GPC
and 500 milligrams of phenethylamine,
and perhaps even 500 milligrams of L-tyrosine,
and perhaps did that alongside
the caffeine and the yerba mate, then yes, absolutely.
I really liked those workouts.
I could be like a laser in terms of focus.
I could exert even more effort, put on some music,
and I could achieve even better performance.
And then I also discovered that I could export that protocol
of caffeine, yerba mate,
and various supplements to my cognitive work.
So, when I was studying, or writing papers,
or writing grants, or in the laboratory,
when I was doing experiments with my hands in those days,
you know, cutting brain tissue and staining it
and working really long hours.
And I discovered that all of those things,
all of those behaviors compounded with my love of exercise
and my love of doing science and gave me these big peaks
in what to me felt like even important experiences.
They felt that, you know, unlike anything else.
They were just so, so peak in their nature,
which was great, and it did indeed enhance my performance.
However, while it did not create a dependency
for those different substances,
caffeine, supplements, et cetera.
What I noticed was that in the days
and sometimes weekends afterwards,
even though for much of my career, I confess,
I've worked weekends as well,
but I would notice that I'd experience
a real trough in energy.
I just would not feel that good.
And then if I kept up those behaviors consistently,
and I was consistently adding in these other,
let's just call them what they are,
dopamine-releasing or stimulating behaviors and substances,
that my enthusiasm for physical training, or running,
or for doing experiments, actually started to diminish.
And this was really discouraging to me at the time,
because I started to think, okay, maybe I'm burnt out.
Maybe I have adrenal burnout,
which by the way, doesn't exist, folks.
Your adrenals don't burn out.
There is something called adrenal insufficiency syndrome.
You can overstimulate your system
by way of too much adrenaline,
epinephrine, and norepinephrine.
But that's a separate thing.
There's no such thing as adrenal burnout per se,
but I didn't know that.
So I thought, gosh, I'm really burnt out.
When in fact, it's now obvious to me what I was doing.
I was combining too many dopamine-releasing
or stimulating behaviors and substances
for things that I already enjoy doing as behaviors,
namely exercise and doing experiments.
Anything related to science actually.
So, what this means is not to avoid taking things
or doing things that amplify your amount of dopamine,
but to be very cautious about how often one does that,
and how many different dopamine-stimulating
behaviors or compounds, one stacks.
Especially, in terms of taking those things
or stacking those things in and around behaviors
that you already really enjoy doing.
I was essentially just creating
another version of the kids in nursery school
or first grade with the gold star experiment.
I was basically, just doing the exact same thing.
And when I realized that,
and I changed my relationship to those compounds,
I didn't eliminate them all together.
But I started realizing, for instance,
that I didn't need to double up on yerba mate
and coffee every workout.
Sometimes I would do one, sometimes I would do the other.
Frankly, I always do one or the other.
It's rare that I ever do any kind of physical training
without some caffeine first.
And I do my physical training,
typically in the early part of the day,
so that's fine, doesn't interfere with my sleep.
I might do a hike without caffeine,
but if I'm in a weight trainer, I'm in a run,
I tend to drink coffee beforehand or have yerba mate,
or if I occasionally meaning about once every third,
sometimes every other,
but usually, about every third workout,
I'll take 300 milligrams of Alpha GPC,
maybe occasionally, maybe every third or fourth workout.
And these are resistance workouts.
Mind you, not running,
I'll take 500 milligrams of L-tyrosine
or more typically, 500 milligrams of phenethylamine,
and very, very rarely, maybe once every two or three months,
I might stack all of those things together
prior to a workout.
But of course, I'm always mindful to also include
workouts, or runs, or bouts of cognitive work.
So, that could be grant writing,
prepping for a podcast, et cetera,
where I don't do anything prior.
Maybe just my caffeine,
because I have a baseline level of caffeine
that I use each day to function like many people.
There's a baseline level of caffeine that just allows us
to function if we're a perpetual user of caffeine.
I talked a lot about this on the episode in caffeine.
But the key here is be cautious.
I would say be very cautious
about stacking and layering in too many
dopamine peak-inducing behaviors
all at once on a regular basis.
The key point here is,
if you are somebody that can engage
in these intrinsically joyful activities for you,
these activities that you're really motivated to do,
whether or not it's skiing,
or playing music, or dancing, et cetera,
without the need to layer in
additional dopamine-releasing mechanisms,
or compounds, or activities,
well then I highly recommend you do that.
Because then you are essentially
making yourself one of those fortunate few
that does not require additional stimuli
and therefore can hold onto that pleasure,
can hold onto that intrinsic pleasure and motivation
to engage in these behaviors over time,
which frankly, there is no replacement for.
There is no pill, or bottle, or potion,
or motivational speech, or podcast, or book
that can replace intrinsic motivation.
Intrinsic motivation is perhaps the holy grail
of all human endeavors and behaviors,
because it encompasses so much
of what brought us to this point in our species' evolution,
and also, what brings each and every one of us
closer and closer to our goals.
And if it's happening with enjoyment
without the need to layer in additional tools,
well then you have really tapped into the source.
And when I say the source,
I don't mean it in any kind of mystical way.
I think it's quite clear by now
that when we hear about qi from Eastern medicine
or we talk about motivation drive and pursuit
on Western neurobiological languages
that relates to dopamine,
or we hear about the source maybe in my podcast episode
with the one and only Rick Rubin,
incredibly productive music producer,
who's as just an unbelievable track record
in terms of creative endeavors.
And he talks about the source.
We're really talking about the same thing,
which is this set of circuits within us
that allow us to identify what we want
and then lean into effort,
and then to do that in a persistent way
that allows us to reach our goals.
And if we can do that with an intrinsic sense of pleasure,
well, that is nothing short of magic.
