Don't be afraid to take a big step if one is indicated. You can't cross a chasm in two small jumps.
Sometimes I can be timid. And yet, most of the major decisions I've made in my life have been spontaneous leaps off cliffs or across gulfs, without a parachute or springs on my feet. And always, always, I have landed safely at the bottom or on the other side.
That's not to say that once I landed there weren't adventures, both good and bad. What I am saying is, the leap into the unknown isn't really the hard part. The hard part is what to do once you get to there. That's when the real work/fun begins.
But then, isn't every day, every minute even, a leap into the unknown, a jump across a chasm of time, for which there is no certainty and no sure landing?
So...are you a cliff hanger-oner or an Evel Knieveler?
