Principles

Just because you can doesn't mean you should.

The ability to act and the wisdom to act are different things.

Don't tell people who you are. Let your work, choices and behavior make the case.

More activity doesn't fix the wrong problem.

Understand the constraint before adding people, money, technology or effort.

Ideas are easy to protect in theory.

The real test is what survives contact with people, pressure, constraints and consequences.

Capability has to be maintained.

Physically. Mentally. Professionally.

You don't get to keep it because you once earned it.
