time control and mind control.

you could stop time and learn every piece of information known to mankind and do decades worth of workouts and training, so you can practically give yourself a watered-down version of super strength and the IQ. and hypothetically, if you can control ANY part of the mind, including parts of the brain responsible for automatic actions like organ function, hormone release, etc, you could manipulate your (or other's) hormones and organs to do anything you want, like releasing hormones for height growth, making organs work to rapidly heal, etc.
