Saving is a big thing, and not touching the money til you have what you need.
Buying/selling/trading can help a lot if you know what your doing. I used to pick up gear from pawn shops for cheap and hustle them elsewhere(good working equipment). Like a couple years back, I traded a $30 cadence 4chan for a cadence ultrashock 4chan and flipped it for 150.
Good deals are to be had everywhere, you just have to know where to look.
