They say "choose the ten things you want to learn, and then cut 7 of them."
Umm. Yeah. I wish it was as simple. Maybe it is. Currently it is still more like I keep 7 and drop 3 xD. But at least, I am not trying to do all of them at once and failing to do anything at all in the end.
Perhaps the cause for it is because you have avoided it in the past?
It is probably trauma. I think I basically was made to believe I suck at it. Something like that, and I never really pushed myself to improve in that area.
