Adapted from "Managing Oneself" by Peter Drucker

"Success in the knowledge economy comes to those who know themselves--their strengths, their values, and how they best perform."

To discover your strengths, do feedback analysis.
Whenever you make a key decision or take a key action, write down what you predict will happen. Six months to a year later, compare the actual results with your prediction.

This will show you the following things: your strengths, what you are doing or not doing that prohibits you from enjoying the benefits of your strengths, what you're not that great at, and what you have no strengths in.

Concentrate on your strengths.

1) Position yourself where your strengths produce results
2) Improve on your strengths
3) Identify ignorance toward other disciplines and open yourself to them when they solidify your strengths
4) Identify and remedy your bad habits that stand in the way of your strengths
5) Don't take jobs or assignments in areas where you have no strength.

Put yourself in the following position:
"Yes, I will do that. But this is the way I should be doing it, this is the way it should be structured, and this is the way the relationship should be. These are the kind of results you should expect from me, because this is who I am."

A fair question to ask of other knowledge workers: "What do I need to know about your strengths, how you perform, your values, and your proposed contribution?"
