Time manipulation, psychokineeeesis, regeneration, and maybe gravity manipulation.
I'd use TK the most, mainly for mundane things like making myself lunch, taking out the trash, etc., but also to pull pranks, like levitating the neighbor's pets and such. Also, I'd use it in just about any fight(psychic power>bullets, knives, and fists).
Time control the second most, namely to go back and make this thread before you(complete with a 'u mad, MushcookieMan?') and to undo most of the mistakes I've made.
Regenration would take care of most of my health. Who needs doctors when your cells automatically repair themselves.
Gravity manipulation would be my 'big gun'. There are (supposedly)ways to defend against psychic attacks, but no one can fight gravity. You bring a psychic-proof giant robot to fight me? I'll just turn up the gravity around it to Jupiter levels, see how long it takes for it to get squished down to the size of a penny.
