Life is sweeter when you carry others alone, no body is complete alone, we all need each other in one way or the other, it isn't good if you care only about yourself, what about your neighbor why not care about them as well..
A lot of people think only about themselves, yes it's good to think about yourself but it is much more better to be someone who others look up to. Good name is better than gold and all the riches in the world, the easiest way to have a good name is to be a helper, a good mentor, someone who inspires others.
A lot of people are gifted with some special talent, some are gurus in their field and profession, in all of this some of this gurus find it very difficult to pass their knowledge to others, what legacy do you have when you leave this world?, Will your name be remembered for good years after your departure to the world beyond?.
What will you gain if you live only for yourself?, Why not shine your light to others to enable them see clearly as you are seeing..
In any way you can do not fail to help others, if we all can practice this then the next generation will have a better future, those you meet on your way up will surely be of help later and they can only help you if you treated them nice on your way up.
