Why do I mention this? Because every time I've been feeling stressed/demotivated/apathetic/generally down, and I want stress relief/motivation/a good laugh, I just pop some of the bubble wrap. It really works.
I'm definitely investing in some of this stuff. It costs less than therapy, anyway. This, writing, math, grammar, and everything else I love should keep me from completely losing it, although I'm getting asymptotically close.
