Failure can be difficult to cope with, but it is important to remain calm, accept what happened, and give yourself time to process your emotions. Do not dwell on others' negative comments. Have courage to try again with a positive mindset. When facing failure, reflect on what went wrong to identify weaknesses and focus future efforts on improving those areas, as mistakes can be the greatest teachers. Overall, do not give up - look for reasons to continue rather than excuses to quit.
