Yes, you need to pace yourself. If you don't, at some point, your body and soul will just say : "stop". And it'll stop you any way it can : depression, chronic pain, extreme fatigue, addiction. I've been there, I went through it, it was ugly and horrible. I'm on the other side now.

Pace yourself. And take life with a grain a salt : However big your achievements, they will all be erased by the sands of time, one way or another.

Ambition and work are good, but not in infinite amounts. Don't overwork, work smart and keep the mental stimulation in check (there are SO MANY tutorials to watch! SO many things to learn!!)

The Machine is made to suck you dry and spit you out. Don't trust it. I personally consider idleness as a political statement.

TLDR : Pace yourself, otherwise your inner system will stop you ---by force.
