Many youth really do not have high expectations and high goals, they settle for mediocrity. They are fine with just being OK or average and they do not set their standards very high.
The unavoidability of death should make us more industrious and hard-working with the time that we have. We should strive to be creative, develop our skills, and contribute what we can to the world. We should not allow our inevitable passage make us despondent or listless. We should not hasten on our deaths prematurely.
