1) The power to rewind time.
Imagine you could go back in time and play the lotto numbers that you already know are going to win. Or going back and correct mistakes you made because you didn't knew any better at the time. One catch tho, Once you go back, you have to live those reminded years all over again at normal speed.
2) The power to pause time.
Imagine you could pause time at will, for unlimited amounts of time. You could make the world "stop" right in the middle of a busy meeting, go take a nap, come back and hit play. One catch, only *you* can live on this "paused" state. All other people are immobilized and unaware that time has stopped.
3) The power to forward time.
Imagine you have job opportunity that pays well, but just hate to do it. You could take the job, fast-forward life for about ten years, quit and enjoy your savings. One catch, when you resume normal life, you instantly age to match the amount of years you have skipped. And if it happens that you die during those 10 years, oh well... bad luck bro.
RULE: You can choose only one.
