I don't usually share insights from particular meetings with my coaching clients but, following on from the Ira Glass quote above, I did see something the other day worth sharing.
One of the reasons that we can feel frustration with our work is that we have the capacity to "know" a higher or deeper level, though in another field or area of our life. We can sense what "deeper is" in one area but not in another. For example, a professional writer who is working on their musical composition chops feels far more frustration than a beginning musician who hasn't tasted the finer air in another field.
In my own case I have this experience with Aikido. In terms of being a musician I am possibly the equivalent of a fourth degree black belt. But in Aikido I am only less than half way to a first degree black belt. Essentially I am an experienced novice. This can be very frustrating for me on the mat, as I can "know" what it is like to be transparent with the moves -- to know that the moves have a life of their own and I simple "leave myself at the door" and let the move do itself -- but I can't. I know this as a musician, but with Aikido I am at a loss. I just don't have the experience under my belt. It may be as simple as the number of hours put in just haven't added up enough to get me there.
This frustration is actually a blessing, as I can "taste" the discrepancy between my capacity and what I know is possible. That gap is a source of energy.
