What can or should i draw?

ok well im completely bored out of my mind and since it's summer im going to just be hanging out with friends and nothing else really so i mostly will be drawing. What should i draw.... im not really into cartoons or anything like that and i also dont like drawing the things i see outside my window cuz thats my naboirs house and i dont want to draw that.... im mostly into drawing things like hands.... lately what i've drawn is 2 hands making a heart, hand holding a beer bottle, a realistic koala bear, and this cool drawing of giraffes with neon colors which i painted in art cl on a big canvas. so any ideas would help! thanks
