Frustration is a matter of setting and meeting expectations. Why is being frustrated seen as a bad thing? After a victory, great coaches are certainly pleased to have won, but most remain frustrated with a number of facets of the contest that fell below expectations. After a day at work, have you met all the expectations that you set? Have you set expectations at all for yourself and those you work with?
To be “frustrated” is to be determined not to simply leave good enough alone. A win is a win. But, only with broad and measured expectations within a frame of performance reference, could it be determined above expectations (aka winning). The next competition or the next problem to be solved may require that other or all of these facets go exceedingly well.
If you are never frustrated with your performance or that of your team, are your expectations high enough?
