Failure is the Mother of Success
It is well known that failure is a common part of life. When we fail, we may feel frustrated or lose confidence, but these setbacks can also teach us valuable lessons. For example, Thomas Edison failed thousands of times before inventing the light bulb. He famously said, "I have not failed. I’ve just found 10,000 ways that won’t work" . This shows that persistence and learning from mistakes are keys to success.
If we face failure bravely, analyze our errors, and keep trying, we will eventually achieve our goals. Remember: Every failure brings us closer to success.
