It’s only a partial truth when you hear the saying, “what doesn’t kill you makes you stronger.” Because the alternative to that is that something could beat you down and wear you out, and if you don’t allow yourself to recover before the next defeat, you’re only going to see a decrease in performance. Too many harsh defeats in a row could decrease your confidence, and instead of making you stronger, it weakens your resolve.
Practice balancing between setting hard to achieve, but still realistic goals and getting some quick wins under your belt (to build momentum and confidence). When you do go for something and fail, prioritize learning from your mistakes and recovering from failures. Just make sure that A) you’re not aiming too low just to avoid the feeling of pain/loss; and B) you have regular stretch goals that are realistic, but definitely not guaranteed.
