If you're wondering what The Impossible Goal is, you can read about it here.
This post is a bit of a nod to the great motivational speaker Zig Ziglar, and I highly recommend his books and material, especially anything he's written that has to do with goals.
When you're in a plateau, or you're exhausted from working so much, or you've got family stuff that's happening, or you're just over it, how do you get the drive, the fire, the excitement that you had before? How do you get enthused about practice?
Now let me ask you this: So what?
Sometimes you will NOT feel like practicing. Feelings are irrelevant sometimes. Sometimes I don't want to drag my butt out of bed at 5:15 am so I can be out the door to get to my job on time. But I do it anyway.
If you aren't feeling the drive, fire, or desire to practice, do it anyway.
Grab yourself by the scruff of your neck, drag yourself to your practice area, plop your butt down on your chair, and DO IT. (I know that of which I speak. My husband's seen me do just that when my cell phone alarm goes off in the evening at practice time.)
I guess this is the bottom line, in my opinion: Feelings and emotions are useful. I've been inspired to practice more after a job that kicked my butt. :) I've been inspired to practice more and learn more briefs after a job that I kicked ITS butt. But feelings do shift and cycle like a river's current, and emotion alone won't get you to 225 or 260 or 280 or 370+. Consistent elbow grease WILL. Eventually.
(Maybe this was less of a nod to Zig Ziglar and more of a nod to Larry Winget.)
