I... suck at writing.
Currently I'm working on a book that is seemingly taking forever to write. I've been coming up with concepts for said book since way back in highschool, but when it boils down to it, I never actually started to write the book until 1.5 years ago. Life gets in the way from time to time, but more to the point, I keep second guessing myself, and running into road blocks.
There are several projects I have on the go as well. Be it programming, music, artwork, or writing, I never seem to finish any of them...
One day. I'll be able to finish them all :)
