For a novice hurdler, it’s tempting to jump up over each hurdle. If you jump up, you’re more likely to make it over each one. If you make it over, you certainly won’t fall flat on your face.
But track and field coaches will tell you it’s more effective to jump out over each hurdle. You start your jump from further back to get more horizontal distance, hence making more forward progress. Jumping out is riskier. It’s more likely you’ll hit a hurdle, and it’s more likely you’ll fall, but it’s the only way to get better.
Isn’t that a lovely metaphor?
