My feelings based on the experiences till date.

1. It always takes few seconds for a person to show the frustration, but it always takes many years to apologize. Pathetic 
2. Be careful while yelling at others, once tongue slipped, you cannot take words back and it takes years to heal the pain and gain the trust. 
3. In order to have control on your body / health one must have control of his / her sense organs. Basic fact of life. 
4. At times we wait for some little things to happen for many hours or days, but it disappoints us in such a way that if hurts for many years. Sad but true
5.
