you can always live longer by adding new friends to your life.

All of your good friends are like steps in a ladder. With one missing, you would have hard time to go up

You can always find out your age by level of your happiness.

Time will age everything except your best memories.

Your success can and will give birth to undesired entities. False Friends and True enemies.

The worst thing you could to your best friends is to help them in something they could do themselves.
