What are the things that are not written in books but we should learn them by ourselves?

                          

1. Only three types of people tell the truth - kids, the drunk, and the angry.
2. If you are the smartest person in the room, you’re in the wrong room.
3. Sometimes the people you wanted as a part of your story are only meant to be a chapter.
4. Don't fall for sweet words. Fall for sweet efforts.
5. Life is ironic. It takes sadness to know what happiness is, noise to appreciate silence and absence to value presence.
6. Nothing will make you feel better except doing the work.
7. Instead of saying “I don't have time”, try saying “It's not a priority”, and see how that feels.
8. You can't get much done in life if you only work on days when you feel good.
9. The days that break you are the days that make you.
10. Maturity is crying alone, wiping your tears and start smiling again.
11. Frame every so-called disaster with these words - “In five years, will that matter?”
12. Truth is a debit card - pay first and enjoy later. Lie is a credit card - enjoy first, pay later.
13. It's never too late for an apology.
14. Too much light usually blinds us. We need darkness for a balance.[1]
15. Everything can change in a blink of an eye. But don't worry, God never blinks.
