i attempt to creatively design my work schedule as much as possible. like i put little rewards at the end of work loads.. like id really love to draw cat hats, so id make a deal with myself that if i can get 10 more pieces of cat furniture done then i can move on to the cat hats.
if that doesnt work ill put a better reward at the end like a game of magic or going to the bathroom.. and even shaving.
if all else fails though and all i have is a bunch of shitty work to do, i just put on music very loud and plow through it!
