Adherence

Adopting a cluster of healthy health behaviors (high physical activity, never smoking, excellent diet, moderate alcohol consumption) is associated with higher energy vitality, lower psychological distress, better self-rated health, and higher quality of life compared to clusters with multiple risk factors.

Don't try to fix everything at once, but recognize that your habits are linked. If you are physically inactive, you are more likely to smoke or eat poorly. Start by improving one area, like adding moderate activity, as this often correlates with better mental energy and vitality. The goal is to move into a 'healthier cluster' (e.g., becoming a former smoker, eating well, and staying active) rather than optimizing just one metric in isolation.
