Some more thoughts... Travelling: Go somewhere you don't speak the language, and where they won't be good at English. Don't do the tourist locations. Find out how other people live their daily lives and reflect upon it.

Perhaps you will want to help people less fortunate than yourself. Perhaps you'll want to help people like yourself because you discover that you are actually less fortunate in some other sense.

At the very worse, don't waste your life on video games and internet, unless you're going to create a video game that might need to be online.
