Yea... I have quite a few...

Starting my breeding collection
Growing chilies...just habaneros for now..both hydroponically and in soil..making the lights and systems for em get pretty expensive
Distillation. Copper is expensive!
Cars - My gtp is a money pit. No joke.
Making everything I have a mild interest in.
CB's
BIKING! - both road and mountain - Everything is so dang expensive!

That's a lot to obsess over, all at the same time, when you are utterly broke. So to answer your question on how I cope when I don't have enough money for them all: I just research and design them, hoping to some day actually follow through on them, lol.
