I spend almost every extra dollar I have on this hobby. I won't look at my order history from Tower for the past year (since I started) but it's in the thousands. Thankfully I can't fit anymore planes, so I sort of stopped looking at new planes. I had to force myself NOT to upgrade the engine in my Venus 40 - so as not to spend the money, but also I know I'd end up justifying a new plane for the 46AX I'd be taking out of the Venus.
I'm 31 too
This hobby has gone as far as to get me behind the sticks of a few different Cessnas, and even do a touch-and-go with a 172.
