Failure is the stepping stone to success.We will be attempting many tasks in our journey. Sometimes we will be victorious. But sometimes we may fail. But we should not get disappointed with the failure. We should try and understand what are the reasons for failure. Where we have gone wrong. Once you understand this, you can rectify those mistakes and re-attempt. Success will be yours. So we should not worry about the failures. We should learn from our failures and march forward.
Science inventions and discoveries may not be done in a single attempt. Thomas Alva Edison took more than thousand attempts to invent the bulb for the first time. Had he given up after initial attempts that invention might have been not done?Once a reporter asked him whether he has wasted his times in his efforts. The reply of Edison is "No I just found a thousand ways in which I could not make the filament bulb." A good reply. Patience and hope will give you success.
