About:
I live my life by the following rules:
- Earn by the dint of your hard work and share with the less fortunate.
- Never refuse help, not even to an enemy when he is down and out and seeking your help.
- Heaven and hell exist on earth only, do things that make you happy n satisfied and experience heaven.
- Do not look down upon others and do not hesitate to become their stepping stones to success.
- Give help an forget about it. Don't expect those you helped to be always thankful.
