After a lot of thinking and self realization, introspection that is, I have finally understood somethings for good. It's worth sharing I guess.

1. 

Don't do something permanently stupid because you're temporarily upset.

You might as well stay calm and control your feelings instead of doing something stupid which will only damage things for you in the future. Calm makes it easy.

2. 

Never regret. If its good, its wonderful. If its bad, its experience.

Someone told me if you really want to stay happy, don't regret your past. What is done is done. If you did something wrong, accept it and apologize. Never repeat the same mistakes. Don't tell anybody that whatever you did, you didn't mean it. It's not proper. And whatever happened, move on and learn from it, bad is also an experience.

3. 

Don't look back and ask why. Look ahead and say why not?

It is better to look back at something you have done than to look back and regret what you have not. At least you have had the experince and now you know you do not wish to do that. Take chances because life is for living and that means doing what makes you happy, never regret something that makes you happy. Think positive about the future and say why not. No regret of the past, total hope for the future.

4. 

Forgive.

Forgiveness has a power. It is an attribute of the strong. It helps you to heal and it is also a key to happiness. Let go!
