At work: Sometimes, if I know there's someone I hate working the next day, I will remove all the paper from the printers, and hide all the staples. In the pharmacy, I get the 500 count bottle of pills from the top shelf and leave the top unscrewed, so when someone grabs it by the cap, the bottle falls and pills scatter everywhere. I haven't had the guts to do this with the liquids, though. It's carpet in the pharmacy.
If there is a child in the toy aisle throwing things on the floor, I quietly start putting ALL the toys on the floor, much to their confusion and walk away from the aisle and watch in the security mirrors as their mother yells at them when she sees what they've done. The best part is when the kid swears up and down it was an employee who did it and the parent is like, "YEAH RIGHT."
I like to drip little drops of soda on the floor at the store, so that when people walk over it they don't slip, but their shoes make that annoying sticky noise.
All of these things makes me feel better.
I'm rarely miserable if I'm at home, but if I am I read, write, draw, crochet, dick around on the internet... pretty much anything except what I should be doing which is actually creating the plush @Trichomes won fair and square. (I swear I have it all planned out, I just have to get started)
Life's too short to sit around and be miserable when you have time to yourself. Snap out of it. Save being miserable for when you actually find that job.
all it's done is given me plenty of extra time to think of reasons to be miserable!
