1. You are the only promised person in your life.
From Birth until Death, you are the only person who you will spend the whole of your life with. Family, friends, lovers, adoring pets, may come and go. Through the good times and the bad times, you are the only person who will be there consistently and definitely. Beating yourself up when you make a mistake and talking down your successes, doesn't serve you. Make the relationship you have with yourself the most important one in your life.
