Exactly!
Change happens only when you slowly tear down old habits and build new ones in their place. That has to be daily, in my experience. In fact, that’s one of the reasons exercise alone doesn’t work — doing something 3 times a week isn’t enough to build a new habit. That’s also why personal training isn’t very effective (unless it combines nutrition and daily habit building, like I encourage and teach in my nutrition sessions.)
Instead, in order to live a healthier lifestyle, you have something to do every day. A workout to do, a lesson to read, a habit to practice, fellow clients and colleagues to chat with. If you want to get in the best shape of your life, ask yourself, “What’s one thing I could start doing every day?”
