It may be a little late but here we go:
1. You won't feel completely loved until you learn how to love yourself.
2. We will all eventually become old. Live and experiment as much as you can right now.
3. You can't always get what or who you want. And it's okay!
4. Love, dating and relationships require empathy, vulnerability and honesty.
5. You can't change no one but yourself.
6. The person who cares more about people, gives more to the world.
7. When in love, every one becomes an idiot.
