“The words "I should have done this back then" are a curse. Whenever they come up, they tangle around your heart and keep you from moving. They bring up all the baggage you carry and dull your emotions. From this point on is a domain where your emotions can't be dull... "I want to get faster", "I want to beat him", "This is fun"... "I want to move forward". You need to have only pure feelings like that, if you want to reach that domain!”
