The act of failing is to fall short of success or achievement. However failure is not fatal nor is it final. "The future belongs to those who see possibilities before they become obvious." Success should not be measured by the level of achievement one attains, but rather in their ability to try and fail, getting back up, and trying again. Because it is those people who have a vision; a vision that gives them purpose, motivation, and the ability to see an opportunity in every calamity.
By envisioning their future they spark a fire of passion within themselves that drives them forward even when disaster strikes. These are the people who are truly successful, because they experience the stronghold of failure, broke through the chains of calamity, and never gave up on their dreams, and attained prosperity.
Adversity often paves the way towards success.
