Resilience defines an athlete's career as it embodies the ability to recover from setbacks, injuries, and disappointments. This characteristic allows athletes to maintain focus, adapt to challenges, and continue striving for success despite adversities. Resilience fosters a positive mindset, encouraging athletes to learn from failures rather than being deterred by them. This quality is crucial for long-term career sustainability and growth, as it enables athletes to push through tough training regimens and maintain motivation during less successful periods. Ultimately, resilience is key to the overall mental fortitude required in competitive sports.
