Far too often, people focus too much on the thing they want to change instead of the habits that formed the thing in the first place.
For example, They try to solve being overweight with doing a lot of ab exercises, without acknowledging that the problem is their poor diet.
To truly reinvent aspects of yourself, you have to find the habit that created that trait in the first place — and then adjust the habit.
Find the habit associated with the thing you want to change.
“A man who can’t bear to share his habits is a man who needs to quit them” -Stephen King, The Dark Tower
