The longer I live, the more I realize that criticism is not necessarily a sign that you're doing something wrong. No, it's a sign you do something right. It's inherent in losers to look at people who are excelling and to criticize them. A while ago on Instagram, I posted a quote by Winston Churchill that said, you have enemies good. To me, that makes the whole thing.
Remember those Public Service Announcements that proclaimed, "Knowledge is Power?" Andy Frisella says it's not true. Education is not complete without experience and application. Mere information will do nothing for you. You've got to put it into action.
