i do somethings like that too.
-like i remark all the letters i write on my notebooks when i feel its hard to read.
-i make beats with my hands and feet.
-i say hi like everytime i dont have anything to say.
-i make lists when i have many things to do but never actually finish them.
-i have to have the volume always in 5 10 15 25 any number from 5 to 5.
-i first wash my hair then my body in the shower always.

thats all i remember, i might do some other things too but i cant remember. i didnt know this could be a problem.
