You have two hands for a reason. You may be using one of your hands to help yourself as much as you can. You do everything you can to better yourself. You try to eat as well, stay healthy and fit, work diligently to further your career.
But what are you doing with your other hand? Are you helping others? Your family? Friends in need? Giving to a local charity? Volunteering? Making yourself available so that others feel they are being heard? Always remember there are plenty of others in need of a hand. Don't focus so much on your own self that you forget. You have two hands for a reason. Use both :-)
