Here are little things you should know before turning the big twenty-fun:

1. Quality over quantity.

Sometimes, less is really more.

2. You can have your cake and eat it too.

Eat it and enjoy it.

3. Fool me once, shame on you. Fool me twice, Shame on me.

Take letdowns and turn them into lessons.

4. People who live in glass houses shouldn't throw stones.

In other words, worry about yourself.

5. Actions speak louder than words.

What one does is much more significant than what one says.

6. Bite the bullet.

Sometimes you will be faced with accepting something difficult or unpleasant. Learn to deal with it.

7. Practice what you preach.

Do the things that you advise others to do.

8. A picture paints a thousand words.

Your appearance speaks volumes. Dress for the job you want, not the job you have.

9. It takes two to tango.

Along with two wrongs don't make a right.

10. Don't bite off more than you can chew.

Don't fill your plate with more than you can handle.

11. Let sleeping dogs lie.

Don't try to fix what isn't broken.

12. Take it with a grain of salt.

Don't take things too seriously.

13. Every cloud has a silver lining.

Difficult times will lead to better days.
