Do You Keep a Poker Journal or Track Results?

Some players write session notes, others use tracking Apps or spreadsheets.
Do you track your results, and has it helped improve your game?

Yeah, tracking helps. Even simple notes or a spreadsheet show leaks and keep you disciplined. But i don't do it, i want to ,but i am too lazy

I play on 5 poker sites cause it would be boring otherwise.
I find it easier to make 20$ on 5 different softwares instead of making 100$ on a single site.

A pen and paper is the only spreadsheet I keep , and track how much I have left until I hit my daily target
