Don’t be afraid to fail. Get out there and experiment and learn and fail and get a rate based on the experiences you have. Go for it and when you go for it you’ll learn what you’re capable of, what the potential is, where the opportunities are, but you can’t be afraid to fail because that’s when you learn.
