Don't ever let anyone tell you that something is too competitive. Once you subtract the people who don't work very hard, or the people who aren't as good as you, your competition shrinks dramatically.
I read this quote at HappyWork.net and to me rings with a fundamental truth. That no one in this world is you. No one has you unique set of skills, knowledge, personality, ideas, thoughts, etc.
Sure, there might be someone similar in many aspects, but you are unique - therefore there is no direct competition for anything you want to do in your life. Many of us travel through our lives wondering whether we're good enough, better than other people, will have success, or any something else we desire. This quote takes it down to a very elemental level - one that most people can understand because we have lived it first hand.
