You have magic powers which you can use at will but you can't reveal your powers to anyone. How are you improving your life?

Let's assume a standard fantasy load out of powers. Flying, teleporting, shape shifting, telekinesis, etc. etc.

You're allowed to, for example, use magic to grow all of your crops big and strong, but you're not allowed to let anyone see you - and you better have a reasonable explanation because you also lose if someone sincerely guesses correctly.
