Travel
Travel with friends, or go alone to a faraway place. When you come to a new land, you will find that there is much more to explore. Being exposed to the culture and people of new land will make you love to learn many good things, and sometimes it will make you love traveling more, thereby motivating you to work hard to be motivated to go travel more often. It is a life worth living for many people including myself.
The most important thing to remember is when trying to determine what you are going to do with your life, and then you need to take action because nothing happens by itself. You have to decide and try everything, even if you hate it or want to do something else. At the end of your life, you won't regret trying something and failing, but you will regret not trying at all. The choice is yours, be determined to do it.
