How many times after being rejected, receiving a "no" do you decide to quit? One of the keys to success and happiness is learning to take a punch and learn from why got punched.
Life is not about being punched, it is about maturing from all the punches so you never get punched again. You never get rejected again. It's about continuous learning, continuous growth in all aspects of your life so that you can live "your life".
Learn to take a punch and realize that life is a numbers game. Eventually, after maturing and perfecting your craft, you will receive the "yes" and "I love you" that you have always deserved.
