Having posted this question you are already in the journey of self realization

When faced with setbacks, I will consciously shift my mindset to see challenges as stepping stones to progress. For example, if I encounter difficulties in a project at work, I'll remind myself that each obstacle is a chance to develop new skills and problem-solving abilities. I'll draw on my past experiences of bouncing back from setbacks, like when I navigated a difficult academic semester by seeking extra help and adjusting my study habits. To enhance adaptability, I'll assess my current strategies and be willing to pivot if they're not yielding the desired results, similar to how I changed my approach to fitness when one routine wasn't effective. Demonstrating grit, I'll maintain my enthusiasm and dedication to my goals despite any initial setbacks, just as I persisted in learning a musical instrument even when progress felt slow. I'll proactively seek out mentors and peers who can provide guidance and encouragement, recognising that their support can make a significant difference in my journey, akin to how I benefited from a mentor's advice during a challenging career transition. Through it all, I'll remind myself that setbacks are opportunities to learn and grow, much like an aspiring chef using failed recipes to refine culinary skills and eventually succeed.

It starts with an inward locus of control, https://en.wikipedia.org/wiki/Locus_of_control

Individuals with a strong internal locus of control believe events in their life are primarily a result of their own actions: for example, when receiving exam results, people with an internal locus of control tend to praise or blame themselves and their abilities. People with a strong external locus of control tend to praise or blame external factors such as the teacher or the difficulty of the exam.[2]

Focus on learning on how to take that setback and analyze your roll in the setback. Now you can turn the setback into a learning opportunity. Adjust your approach to optimize the odds of success in your favour for the next iteration.

It is also critical to realize there are two types of games in life.

1) Finite Games: Known players, fixed rules, an agreed-upon objective (e.g. baseball). In a finite game, there is a clearly defined end point and there are winners and losers.

2) Infinite Games: Known and unknown players, changeable rules and the objective to keep the game in play (e.g. the cold war). There game ends when someone stops playing

Life and success are Infinite games. Failure or set backs only become permanent if you stop playing. If you keep trying and learning from your mistakes, setbacks become a temporary state.
