Four research-backed motivation findings with practical implications.

1. Autonomy, competence, relatedness (SDT). Deci and Ryan's self-determination theory: motivation is strongest when you have choice, feel capable, and feel connected. Engineer all three into your goals.
2. Interrogative self-talk outperforms declarative. "Will I exercise today?" produces more follow-through than "I will exercise today." The question engages, the declaration lectures.
3. Implementation intentions (Gollwitzer). "If X happens, I will do Y" statements dramatically increase follow-through versus vague goals.
4. Fresh-start effect (Dai et al.). Behaviour change is more likely at temporal landmarks — new week, month, birthday. Use them deliberately.

Four findings, each immediately applicable. Motivation isn't mystery; it's a set of conditions you can create.
