notch down.

In the best of words: differentiate what you want and what you need.
Profound and surprisingly overlooked. It simplifies a life that wants so many things.
And cheerfully agrees with the fact that you "can't have it all".
I would think that the person who achieves this level would be a very peaceful person. Presuming he obtains what he needs. Think about it. It would be so easy to arrange life's priorities:
1. what you need and want
2. what you need
3. what you want
Of course, nothing is that simple. But once the frustation exhausts itself, once the turmoil dwindles, the options continue to escalate and the sadness still lingers, you need to arrange things in simple little boxes and make a straight beeline for one which makes you happiest.
Because in the long run, you only hit what you aim at.
