Nobody knows the outcome of tomorrow; but when tomorrow comes and the outcome of today is clear, don't regret anything. If you see something as a mistake or feel the need to regret something, then stop, and take a deep breath, because the decisions you made were right for you at the time. Therefore, view them as a learning experience and let them influence you're decision next time that situation arises. Regret= sadness and pitty, while learning from mistakes= personal growth.
