Question

The most important requirement for changing an established habit is:

desire to change
avoidance
concentration
consistency

Answer 1

I'd say desire to change.

Step-by-step explanation:

If you don't actually want to change that habit, it's not going to work if you try to stop doing it. You need to have the right mindset and you need to be determined or at least want to stop the habit for it to actually work.
