How would you live your life if you will die at age 20?

Original:

If I know that I will die at age 20, I will live my life the way I want to live it. I would like to travel around the world to places that I want to go, meet a lot of new people, make friends and have good memories. Also, I would want to buy everything that I want, not hearing what other people say and not bother to look at the cost.
