Easy. Just set up your own charity, the "Give Me Money Charity," donate it to that, and keep all the money.
Something similar to this has already been done, but oh well:
You can shapeshift into any animal, but as soon as you do, you no longer have the brain of a human and thus cannot think like your previous form or even comprehend your memories. Likewise, if you ever change back, your memories of your time as an animal would only make sense if you had those animal's senses to perceive it with, and therefore would be incomprehensible to you.
Or how about this?
Every time you breathe out, you move one second forward in time; every time you breathe in, you move two seconds back in time.
