Don't let so much reality into your life that there's no room left for dreamin'. Don't never interfere with something that ain't botherin' you none. Don't worry about bitin' off more than you can chew. Generally, you ain't learnin' nothing when your mouth's a-jawin'. Go after life as if it's something that's got to be roped in a hurry before it gets away.
Good judgment comes from experience, and a lotta that comes from bad judgment.
If it don't seem like it's worth the effort, it probably ain't. If you find yourself in a hole the first thing to do is stop diggin'. If you get to thinkin' you're a person of some influence, try orderin' somebody else's dog around. If you're ridin' ahead of the herd, take a look back every now and then to make sure it's still there. It don't matter so much how long a ride you have, as how well you ride it.
