You could be the fastest athlete, talker, or engineer when it comes to practicality, but faster in practice doesn’t always translate to getting the right things done. It only means you’re faster.
Experience is what often gives you real speed because you learned you don’t have to go all out at once only to find that you got burned out in the middle of the race or project.
Experience means that you pace yourself. You think and make a plan. You review your plan and calibrate expectations of what’s logical, practical and realistic before executing it.
That’s what experience provides.
