A focus on results may yield short-term gains. However, those gains are at risk and compromised when people feel pressure instead of autonomy, disconnection instead of relatedness, and a sense of being used without a sense of the competence they have gained.
The evidence is clear: people can achieve the results you want, even if their psychological needs are thwarted in the process. But their negative energy and lack of well-being make it rare for them to sustain or repeat those results –– let alone exceed them.
