In my perspective, we should not invest all our time and energy into one goal
without doing a kind of assessment regularly. Moreover, sometimes we can realize
that the choices we made are not the best for us, or the path we took won't be
fruitful and won't bring success. Giving up an activity does not mean failure,
it may be a wise and smart decision, person who could predict potential risk
early and change the direction of their ship have more chance to win in the end.
