You have a choice to live your life as is...
or roll the clock back, have all of your memories wiped, and live a life unknowingly destined towards glory at the Olympics Games (gold medal, world number one status in at least one sport over many games).
However, the cost is that your childhood will be destroyed because they will be restructured by your parents and trainers to push you to max potential. Your whole life will be structured and guided by subconscious forces that lead you to your destiny... ultimate gold medal glory. After that goal is achieved, you will suddenly feel free and you can do whatever you want (though your life have been impacted by your dedication to the sport).
So what do you say? Is this a good deal? Please justify.
