Yeah...it's really important to find some job that you like, since if you like it it doesn't feel like working at all :)

Even if I do have a million thoughts in my mind whenever I try to sleep, the brain will still know the priorities and dump them and doze off later...but still I can tell that insomnia sucks. I have a few friends with this problem too. I would suggest using a very strong night filter for your screens and prevent too much white light before you sleep, they really hurt the sleeping feel. Lastly, when you are running your thoughts - do not think of why you won't sleep - that is really fatal to your night of sleep lol. Probably, also try to express your thoughts out in whatever way you want...drawing or writing? Once you empty your mind it should feel better :)

Gotta love sleeping, who doesn't?
