“Life is no straight and easy corridor along which we travel free and unhampered, but a maze of passages, through which we must seek our way, lost and confused, now and again checked in a blind alley. But always, if we have faith, a door will open for us, not perhaps one that we ourselves would ever have thought of, but one that will ultimately prove good for us”
A.J. Cronin
Even with the greatest of care and planning, failure is common. To achieve what can be called success, it is important to have a positive mindset of "Don't worry, we'll work it out" and the ability to continue to take on challenges without fear of change or difficulty.
