Can't find the bug for hours. Next day find it immediatly.
Sometimes try and get some distance to your code.

Yeah. Sometimes it's just a matter of relaxing.

I have my ritual of a "debug smoke" if I'm stuck with a problem, where I go outside, have a smoke, watch the people down on the streets and force my mind completely off my code. It usually results in a "You're a fucking idiot" - moment when I get back and read myself into it again.

@Godisalie not very healthy :D I had the same with a new cup of coffee. Also not very healthy :P

@g3t1t Live fast, die young, leave a pretty codebase.
