If you are interested in building better habits, James Clear is a guy definitely worth checking out. Besides his course from The Habits Academy, I would absolutely recommend checking out some of the other resources James has:
- Atomic Habits (https://jamesclear.com/atomic-habits), a fantastic book packed with evidence-based self-improvement strategies
- The 3-2-1 Thursday newsletter (https://jamesclear.com/3-2-1)
- His blog (https://jamesclear.com/articles)
