What is your favorite skill that you taught yourself and use everyday?

I have taught myself a lot. I love learning new things, so I am always looking for opportunities to learn. But most recently I learned I learned how to create websites with WordPress and I am finding that to be useful for me and others because I can help others create or fix their websites – and for myself too because I can expand upon my offerings.
