I want to buy shit. I have a craving for cool shit.
How old are you (out of curiosity)?
I suggest saving the majority of it for a day when you are in any trouble or need it for an actual decent reason.
Say you spend it all/most of it on "cool shit" that you don't really need. Then one day you run into financial trouble and would have wished you didn't spend it on cool shit that really won't do much for you.
I'm not saying don't stuff that's cool and fun, I'm saying don't waste all of it.
I think it's ok to sometimes buy something nice for yourself, but be considerate. Don't spend everything keep a good amount but a nice treat for all the savings isn't a bad idea. It motivates me to save money. There are a lot of practical things you could buy. Most people here seem to want to learn to hack games, so if you are one of 'm, why don't you buy c++ primer. (NOT c++ primer plus) it's a great start and I finished it a year a ago and it has helped me a lot in many programming ways.
