Is it just me? WTF nothing sticking?

Is it just me or is it ADHD in general?

1. I find some methods/frameworks/techniques that make me productive, that literally work and I get so excited. And then boom, it just becomes absolutely useless. As if the technique never actually worked. Sometimes takes a few hours, sometimes a few days, but never really lasting a week.

2. The same about interests. Something i've been interested in badly for many, many years. And yet when I try to commit to it , it's like I'm not interested in it anymore. Even almost have hatred towards it.

Maybe I have bipolar? :D
