Well, I spend money to take Hot Yoga classes, in addition to my gym membership, but I love it so much that I ended up going 3 times last week. I feel great doing it.
I went back to school for my masters, which I just completed. Even though I now need to get a job, I feel like I have many more skills and knowledge. It certainly helps my confidence.
I also - and this was partially due to a class I took for school - started reading romance novels. I used to somewhat scoff at them, but now I find them to be a total pleasure and a great way to unwind. Also, it sure doesn't hurt relations with my husband!
