When we frame problems as so big that there can be no possible way for them to be solved, we are actively positioning ourselves to be small. This is how we make it someone else’s problem—“What can I do? I’m just one person.”
Contrast that to a small role. A small role can make a big difference in a large scheme. Everyone has to do their part in order for this thing to function or to get better.
Think of it this way: Is now the only time to lead when we are called upon?
