Isn't it the striving, the need to move from one circumstance to the next, is what propels us forward?

People don't make progress in spite of their struggle, progress is made because of the struggle.

This is a very good point. Regardless of talent or luck, the person who is willing to keep trying dramatically increases their chances of success. Someone who only applies for one job and stops if they don't get it, is much less likely to get a job than someone who is willing to apply for 100 jobs until they get hired.
