I came across this thing. Totally makes sense:) i must learn from it man!
1. Don't compare your life to others'. You have no idea what their journey is all about.
2. Don't have negative thoughts of things you cannot control. Instead invest your energy in the positive present moment
3. Don't over do; keep your limits
4. Don't take yourself so seriously; no one else does
5. Don't waste your precious energy on gossip
6. Dream more while you are awake
7. Envy is a waste of time. You already have all you need..
8. Forget issues of the past. Don't remind your partner of his/her mistakes of the past. That will ruin your present happiness.
9. Life is too short to waste time hating anyone. Don't hate others.
10. Make peace with your past so it won't spoil the present
11. No one is in charge of your happiness except you
12. Realize that life is a school and you are here to learn.
Problems are simply part of the curriculum that appear and fade away like algebra class but the lessons you learn will last a lifetime.
13. Smile and laugh more
14. You don't have to win every argument. Agree to disagree.

honestly, it makes a lot of sense(
