How do I build healthy habits that actually stick?

The key is to make habits so small they feel almost too easy at first. Attach a new habit to something you already do consistently, like doing two minutes of stretching right after you brush your teeth. This "habit stacking" removes the need for motivation or willpower. The other critical factor is reducing friction. If you want to exercise, sleep in your workout clothes or keep your gym bag by the door. If you want to eat better, prep food in advance. Your environment shapes behavior more than your intentions do. Track your streak visually, because people naturally avoid breaking a chain they've built. Expect to miss occasionally and plan to resume immediately rather than waiting for a fresh start.
