There's that, but I usually think "Man I must've been really unfocused or otherwise distracted to write it like this" but then analyzing it, it starts make total sense. But there's also the opposite. Code where I can't believe I was so smart to write. And then I remember that I can solve any problem if I keep attacking it time and again and tune my brain to it.

My performance is like a wave, sometimes I'm riding it, sometimes I'm being overwhelmed by it.
