Time flies. Seasons change. So do people. Do you ever look back and wonder why you did or said the things you did? I do. I look back on my past and question my thoughts and actions, but then I dig deep and realize why I did those things. Reading journal entries from my past are almost embarrassing sometimes. For instance, I blush when I read every detail possible about a boy I had a crush on- then look up and realize that I'm only embarrassed for myself. I recall mistakes I have made, or cruel and unkind things I've said. I learn from these.
Look back on your life. Don't regret anything. No matter how stupid or silly things seem to have been, don't say that you wish it hadn't happened. You will find that if you use your mistakes as tools of learning- you will be a happier and wiser person. We are what we are mostly because of the choices we make and how we react to the world around us. If you don't want to have regrets, then act in such a way that you could never regret it. Be the kind of person who looks back on oneself and thinks, "I've had a good life." Be your best. Live without regret.
