Chameleons look in two directions at once and change colors when they're under stress.
Some vision statements are like that.
A company with a blurry identity, a wavering sense of purpose, and goals that are out of focus, may try to be everything to everyone. A vision statement has no value if you don't have a vision. Other companies have eloquent statements of purpose with no heart. All of a sudden, Number One doesn't count. A vision statement has no value if you don't live it.
