Anxiety is not a rational process. That nervous feeling you get before public speaking or cold approaching -- the pit in your stomach, the clammy hands -- it isn't logical. When your body thinks it is in a stressful situation, it will react as if you are being chased by bears, even if you are in Central Park and the closest bear is in the Bronx Zoo.

I suffered from such "physical anxiety" for as long as I can remember. I was never really a nervous person: I don't hesitate before talking to women and I am a good public speaker. Yet, despite a tremendous amount of time intentionally exposing myself to discomfort, I was still getting shaky hands. I was still feeling cold in my extremities.

My immediate problem? Drugs. I regularly used drugs like caffeine, modafinil and phenibut. But that was only masking the real issue.

I recently got tired of it and quit everything cold turkey, and the results were astounding. It sucked at first, since I was used to getting away with short circuiting physiological systems like not sleeping enough.

But now I don't shake, and I shouldn't be surprised, really, since we already know that we aren't better than biology. It's hard to eat right, and to sleep enough, so I refused to actively think about the way I was physically abusing my body by "cheating". I thought I could use my big brain to think my way out of not taking care of the physical, kind of like all the newbs think they can logic their way into some pussy without doing the work. (Because I have your attention and I like linking stuff, read this too. And this, because TRP has a reputation to maintain.)

But the truth is that it's not realistic to expect to succeed by just going to the gym, squatting 5 sets of 5, and calling it a day. You need to sleep. You need to eat well to give your body the nutrients it needs. You need to drink water. You sexual contact with women. I don't care what Jesus (or, in my case, a guy with a hat and beard) tells you.

It doesn't matter how much you practice stoicism. It doesn't matter how much you meditate. It doesn't matter how much philosophy you read. You cannot think your way to physiological health.

Take care of the physical; everything else will follow. And don't just take my word for it.
