1. Save thousands of lives by donating to charity (it costs about $2000 to save a human life: http://givewell.org/international/top-charities/AMF).

2. Do whatever you wish to do, every single day, such as spending a year studying philosophy while travelling the world, or deciding to learn salsa for a year and a half.

Not spend the next 34% of your life working on something you don't love, for one. Even in our current technological state, a life of toil on things you don't love is the default state of a human being.

Or you could learn how to love the things you are already working on. That option is easily overlooked.

I wish I could up vote this more. Our society trains us from birth to constantly be wanting at the expense of ever being satisfied. It is possible to be very satisfied with what the rest of the western world would say is a "crappy life". And then life can only get better.

True, though that option is also a lot easier with a bunch FU money as a back up.

Then spend it on a good life. Give the rest. According to study, you only need $75,000 to live happy. http://blogs.wsj.com/wealth/2010/09/07/the-perfect-salary-fo... Btw, I am not sure why my first comment was downvoted.
