Oooh that's a really hard one.......teleportation would get me to Fadr--er--uh.....wherever I'd decide to go faster but I feel like flight would be a more pleasant experience, so I guess probably flight.
Sometimes mindlessly eating oyster crackers helps me do better on homework, idk why. Or listening to chill classical music. Or you could try sitting in different places, like instead of just being at a desk or a table, you could try sitting on the floor or in a hammock if it's warm enough. Just a change of scenery can help. Also one time I was kitty-sitting for my cousin and the kitten was just in my lap asleep so I literally couldn't move so I was like "might as well keep doing my homework" and that might be the most productive I've ever been, so cats asleep on laps can also help.
