I have seen this numerous times and always stop, pause and ask myself the same question. The idea of failure holds us back from things we would like to achieve. This could be in anything we do; our jobs, love, financially, emotionally and physically. If we took the leap, if we took the chance and only knew we would be successful, we wouldn't pause and we would go for it. Each day is not a guarantee so there is no reason to ever worry about having regret. No matter what you attempt, you have already succeeded because you made the attempt. The attempt, no matter the outcome, is success. Never let failure come into the question.
