For many years I have lived by this philosophy:
It's better than it was, and that's good enough.
I realized, however, as I mentioned this to my employees (I was a manager at the time) that it didn't quite sound the way I envisioned it. To read it as is, one may think that I am advocating inferior quality as acceptable, so long as it is a little better than the absolutely pathetic quality previously found.
While I suppose this may be part of it, I read it to say that if you are continually improving, and always striving to be better than you were before, you're going to do just fine: you can't give anything more than your best continual effort.
I've since discovered that, not surprisingly, President Hinckley advocated this same principle, but said it much more eloquently:
Try a little harder to be a little better.
And that's what I've been saying all along...
