The first 25 years you measure success with grades, only to realize that the real value is in learning to learn and critical thinking.

The second 25 years you measure success by how much money you made, only to realize that how you spend time, and with whom, is most important.

The third 25 years you measure success by how often you opened doors for others, and the joy that came with showing others a path to a better future.

You measure success by the quality of friendships.

And this is exactly the right measure of how to live a recommendable life.
