I realized that with all my time, I don't spend it well enough. As a result, I'm going to accept certain challenges to do stuff, under certain requirements.
1. It only requires me (and the challenge, if he/she wants to participate).
2. It doesn't require me to spend money.
3. It doesn't require me to break any rules or laws.
4. It has to be something unique and actually requires thought.
5. I require the right to decline any challenges.
