If you are writing about things you care little for, you are likely not to finish them.
unless you are ADD and cant concentrate long enough to write anything because you change your mind and start writing about something else then get into a discussion about food then listen to a show that inspires you to rearrange your PC photos and call your sister and then it's time to make dinner and wait wasnt i writing about pachyderms or was it art tiles anyway its too late oooh look at the sunset i need a photo but my camera needs charging and i should take a walk... maybe tomorrow.
