A ladder is what we use to reach something that we perceive we cannot reach with out it. The something is beyond our normal reach. We determine what we want to reach. We decide whether we can reach it on our own. If we can’t reach it on our own, we need a ladder.
It’s interesting that when we look at our careers, goals, projects and stuff in our life, our success depends on the ladder that we choose to climb in order to reach that personal destination. It is a success ladder. This is not any different than selecting the right ladder to reach the top shelf in the garage.
