Passion for learning
A second career doesn’t have to be a professional one. We need vocations apart from employment.
We focus too much on learning or getting degrees for work. Work, as always, drives lot of our desire for self-improvement.
We should challenge this inertia. We must encourage ourselves to get into new fields as a way of personal growth. Maybe those explorations will have a professional applications, but we should make that a secondary goal.
We need to regain the passion for learning.
