On the topic of Habits, I liked the “Habit Loop” a lot from the Atomic Habits by James Clear. It's very simple and eye opening. Not sure how easy and effective to apply though.
The Habit Loop:
The Habit Loop:
- A cue triggers a craving
 - The craving makes you want a reward
 - You respond to get that reward
 - The reward satisfies your craving
 
To help with building a habit:
- Make it Obvious (cue)
 - Make it Attractive (craving)
 - Make it Easy (response)
 - Make it Satisfying (reward)
 
To help with breaking a habit:
- Make it Invisible (cue)
 - Make it Unattractive (craving)
 - Make it Difficult (response)
 - Make it Unsatisfying (reward)
 
A very good “visual” summary of the book:

Thank you Andrew Nalband for the amazing summary!
