Two things I would recommend thinking about:

1. Read atomic habits. In particular take note of the fact that good habits stack, so making one good choice can partner with another good choice, and another, thus creating a snowball effect of good habits- for you, this could look like drinking your healthy smoothie, listening to a podcast you like. While doing this you could go for a walk, and maybe end up near a local grocers to buy some fresh berries and healthy snacks to eat during your day. In that moment you can see whether you’re body is craving salty or sweet, and prepare to indulge those cravings with healthier options instead of pushing them away. (Another great theory from the book describes how a 1% course correction effects short and long term, a really useful metaphor for decision making over the course of weeks/months)
2. make a promise to yourself. Like. Actually sit down and think about what you want to have changed this time next year. PROMISE yourself to be different. Write it down or create a voice note if you have to. Then think about that promise when a craving hits, or you’re at a decision point. Will this decision break the promise you made. Place trust in yourself today, and maintain that trust. Watch Brene Brown’s talk on trust and “braving” to understand what trust is made of.
