Success can sometimes lead to failure because it can breed complacency and overconfidence. When we achieve success, we may become comfortable with our current level of achievement and stop pushing ourselves to improve. This can lead to stagnation and a lack of growth.
Also, success can sometimes create unrealistic expectations and a fear of failure. When we experience setbacks or failures after a period of success, it can be particularly challenging to handle and can lead to a downward spiral.
It's important therefore to remain humble, stay motivated, and continue to challenge ourselves, even when we experience success. _/\_
