What happiness is?

Happiness is relative. It varies between persons. To me happiness is,
1. Watching a baby smile from heart.
2. Flowers in full bloom.
3. Reading a book on a relaxed off day while hearing Elvis Presley on the system.
4. Watching the rains.
5. To talk for hours with the person whom you love a lot.
6. When you spend time with your sweetheart.
7. While I am with children.
8. Going on a trekking in a wild forest. Staying at a treetop hotel and looking at the stars at night.
9. When someone says that I have lost weight.
10. To drive at 120 kmph on a national highway.
