Schmidt and Rosenberg agree that one of your everlasting career goals should be finding a way to not only love what you do, but do something that provides you with a comfortable life and makes an impact on the world.
There are lot of definition about contribution. Maybe, some will think about giving in charity, or shares knowledge, or the simple one, shares the happiness. People have their right to choose, which method will they do to contribute, makes an impact on the world. I simply understand the word 'contribute' as simple step called 'share'. I believed that peoples should share what they have, in their present capacity. Even a simple knowledge can be shared.
