To succeed and overcome adversity, one must shift from an amateur to a professional mindset by flipping a 'mental switch': this involves being consistent, taking action regardless of one's moods, not taking failure personally, and continuing to move forward despite fatigue or pain.

The idea of adopting a rigorous stance to overcome obstacles resonates with the concept of 'grit' from researcher Angela Duckworth, whose observational studies associate perseverance with long-term success. However, a major meta-analysis by Credé et al. (2017) suggests that the impact of this tenacity is often overestimated and that it is primarily akin to conscientiousness, a relatively stable personality trait. Furthermore, the notion of an instantaneous 'mental switch' contradicts behavioral science (such as the observational study by Lally et al., 2010), which shows that anchoring a new habit requires a gradual process of several weeks. Regarding setbacks, the work of Carol Dweck on the growth mindset supports the idea that learning not to take failure personally helps one bounce back, even though the meta-analysis by Sisk et al. (2018) shows that this impact on performance remains moderate. Finally, the injunction to 'play injured' by ignoring physical and emotional sensations is risky: research on burnout (such as the expert consensus by Meeusen et al., 2013) proves that systematically ignoring these warning signals harms long-term performance and fosters overtraining.
