It's never enough.

Cecil Rhodes, former Prime Minister of the Cape Colony of South Africa and founder of the De Beers Mining Company, the Rhodes Scholarship program and the state of Rhodesia (later separated into the nations of Northern and Southern Rhodesia and later renamed Zambia and Zimbabwe), uttered these final words on his death bed: "So little done, so much to do."

This is my greatest fear:

Regret for what I could and should have done.

It is also the reason I do not plan on dying.
