Nothing seems all that important to me. Not all the time - in fact usually whatever happens to be right in front of me at any given moment will seem quite important. I can waste hours doing nothing... focusing on tasks that have no purpose, feeling anxiety for the impending lack of purpose upcoming when I get done with what I'm doing. Eventually I look back on my day and think "wow, that could've gone better"...
I always remember the important responsible-adult type things I need to accomplish at times I deem useless for accomplishing anything. Once I'm done with whatever I "had" to finish I'll be so caught up in the anxiety of impending boredom (and how to fix it) that I will totally forget about what I needed to do. By the time I remember I've thrown my attention at some pointless endeavor which begs completion before I move on. Yes, just a few more hours of watching physics videos on youtube before I find a new diversion for my attention.
A guitar leans on the small end-table by my bedroom door. Always there to beg me to play for a half-hour instead of doing whatever it is adults are supposed to do. So we spend an hour together playing other people's songs... sometimes I think it sounds just as good as the original, sometimes better - but it's not my song, not my creation, just another distraction.
Melodies and lyrics love to find their way into my head as I am about to drift to sleep. Nothing wakes me up faster than "holy shit that's cool I should write that down!" - "no dude, fucking go to sleep, you have to work in 4 hours. there's always time to write why do you want to do it now? what the fuck is wrong with your brain? what the fuck why does my brain hate itself.... fuck, now i totally forgot that cool lyric/melody i was going to write down" - "asshole" .... yep.
