There is only one way to avoid criticism: do nothing, say nothing, and be nothing. -Aristotle (i. you can't avoid criticism so you must just learn to accept it and go on with your life. Accept yourself flaws and all).
Twenty years from now you will be more dissapointed by the things that you didn't do than by the ones you did do. So throw off the bowlines, sail away from safe harbor, catch the trade winds in your sails, explore dream.
