Do you have anything you do to occupy your thoughts? Like when your stuck doing something repetitive or you find yourself incredibly bored. I tend to create things, like challenges: think of something that works in a certain way, break some essential part of it, and try and come up with a solution that doesn't involve replacing what was originally removed. Another thing is listening for definite statements, like whenever I hear someone say never or always I like to try and come up with an exception. Do you do anything similar? If not, is there a particular something you tend to think about more often than other things?
