That's basically diffusion versus drift.

But I think it is the wrong view, as generally people do move into the direction they want to go. Take a person doing plumbing but wanting to be in art. The problem is not the direction, the problem is taking the first step.

In general, many people dislike changing jobs, so they don't take steps. The steps are the problem, not the direction.

You don’t know anyone in your life that “talks big game?

Or someone else that “can’t get their stuff together?”

A lot of people never even “move”.

Drift made me think of electron drift under applied voltage or electric field.
