A valuable way to conclude this chapter might be Henry Ford's comment about it.
Read their words and see how they relate to you: We started out as pensioners, some people live two-thirds of their life with what others provided.
We graduate as cooperators, we earn our own livelihood, we do our share of work, we produce a little extra for the pensioners who come after us. Some go to the third stage, where they do a little more for the world than the world does for them, and they make the world their debtor, by making everyone live a little better, or their hopes are greater, or your broader opportunities.
Just carrying your share of the burden is a great and satisfying thing; it makes one feel like a man. However, that is nothing more than tying the board; But doing more for the world than the world does for you is success.
