It's driving me crazy, every time I feel like I improved and learned something more, I get discouraged by a very bad session.
And I can't tell if I'm bad and just getting lucky on the good sessions or I'm actually improving but today was a really unlucky day.

I read books, pot hands, etc but I fear I might be a degenerate in denial. Or maybe I'm just impatient and gotta keep at it since i'm actually improving.

How do I tell?
