Want to second the drinking/bar/club/happy hour comment. It turns out that drinking is a surprisingly cheap hobby, but as mentioned it has little return.

At about 24 I consciously ended that period of my life. At 27 I have my scuba certs, pilot's license, a piano that I'm finally learning to play, a hang glider, a 4x4 which I used to take off road regularly before I got all the other stuff, etc. These have even led to several related career opportunities.

The only caveat is that these things do take money and time, and you will need strike the right balance with work. If you find you don't have enough time for something, cut your losses and focus more on what you do have time for. It's probably more important to you. I'm only just now selling the 4x4 ...
