Do the job.
"Am I through? Am I thorough?
'A job worth doing is worth doing well.' -Newman
'A job worth doing is worth doing poorly.' -Chesterton
Just get the job done!"
I'm not really sure how to take this. The first quote by Newman seems to be referring to when you have something to do, it is wise to do everything you can to perform it to the best of your abilities. The difficulties that may arise from this is something that I struggle with very often, which is that I am so focused on having a large amount of time to work on something that if I can't carve out 3 hours to work on music, I won't do it at all. The problem with this approach is that it's really easy for me to figure out ways to keep myself from making ANY length of time to work on my music, so then I get to the end of the week and realize that I haven't practiced my drums at all or worked on any of my arrangements/compositions at all. If I would just put 10 minutes into my music each day, I would have put in over an hour of work into my music by the end of the week. 1 hour a week is better than no time at all.
The next quote by Chesterton seems to be the angle that I'm implying in my previous explanation. If I want to get to work on the art, reading, exercise, volleyball, drumming, composing that I so want to do regularly, it would probably be a better plan of attack to just get to it and expect it to NOT come out well. I once heard from the great jazz saxophonist John Ellis that he composes everyday no matter what. He says that most of when he writes he doesn't like and does not end up being a tune that he follows through with brings to his band to perform and/or record. But the point is make sure that he is constantly writing so he is always creating, even though he knows that much of what he is writing may not become the next number one single on the jazz charts.
So it seems that I do understand how this message is supposed to relate. Look at my goals and work on what I can work on to the best of my abilities but also be open to the possibility that it may not be the most amazing stuff I've ever done. The journey is just as important (or maybe more important) than the destination.
