I lack concentration, getting bored easily, and thus also move from one thing to another. Sometimes I don't bother even trying. I thus spend a lot of time just sitting and doing nothing. This particularly bothers me as I am (or was) somewhat of an artist. I lack any inspiration or creativity and now don't even bother getting out my supplies at all.

Medication. I'm not sure which of my medications is responsible; but, I blame them for deadening my interest in things and killing any motivation or inspiration for creativity.
