“Note that this journey is uniquely yours, no one else's. So the path has to be your own. You cannot imitate somebody else's journey and still be true to yourself. Are you prepared to honor your uniqueness in this way?”

The Rickover Effect (1992)
Context: Responsibility is a unique concept... You may share it with others, but your portion is not diminished. You may delegate it, but it is still with you... If responsibility is rightfully yours, no evasion, or ignorance or passing the blame can shift the burden to someone else. Unless you can point your finger at the man who is responsible when something goes wrong, then you have never had anyone really responsible.

We all tied together. [... ] Everytime you cut off somebody else's opportunity you shrink your own horizon.
