Great Investment/Life advice

I was reading this article over on Yahoo Finance about athlete-turned-entrepreneur Roger Staubach and his mention of coach Tom Landry:

Staubach's role model for planning was Cowboys coach Tom Landry. "Coach Landry was a great leader," he says, "and his greatest strength was in preparation. He was an industrial engineer. He had carefully set goals that were reasonable, believable, achievable, and measured. His philosophy was that spectacular achievements come from unspectacular preparation.

That's really something you can take into your life. It's something that I've seen mentioned in writing and in boxing, but when you think about it, what does this NOT apply to?

Spectacular achievements come from unspectacular preparation.
