Failure and success are part of a man's daily life. We either fail or succeed, and they both can be a stepping stone or a crumbling block, it all depends on the attitude of a man in each state. Most successful men suffered failure, it was their attitude toward failure that became their strength. Some considered failure as a process of learning, like Thomas Edison, while others perceived failure as an indication that they're doing something. Either ways, they moved beyond the discouragements that came with failure until they succeeded. Several philosophers believe we can't be true winners without passing through the pain of failure, i.e, one can only become genuinely successful if he had experienced failure.
Success on the other hand can either come as a result of persistence or luck from the gods. The latter is believed to never stand the test of time having no knowledge of what works or doesn't, and probably not have the stamina to endure difficult times. A man who has never failed and one who had failed severally in the past handles tasks differently. It is believed that one works with experience and the other from trial and pride of mastery. In as much as there's joy in success, the price paid to attain such success is what makes the story beautiful.
Failures sometimes are meant to build us up. The pains itself are lessons and sometimes they're indicators that remind us of our weakness and stir us toward improvement. While I was in school, the only moments I felt challenged to study hard were the moments I failed either a test or a question directed to me. If there's no failure, then we may never see the need to improve. The reason why technology had grown this wide was because the older technology was failing in one particular area that needed improvement. If no failure is dictated, no improvement is required , and that's the reason why men who had failed in the past and have risen up are believed to be more improved than people who had never failed.
