Amen Master, Amen .
Why spend money on other hobbys that you won't enjoy AS MUCH.
I like Parkour and free running, which, well, it's free. Just need a good pair of running shoes, and non loose-fitting clothing.
Apart from that, there is Basketball, and Soccer. And that's it.
I need a good cash flow to get my PC upgrade fix every now and then, but that's the extent of my spending. Oh, and Junk Food. >:|
