If your habits determine your health, you should focus on these daily activities to change and eliminate bad habits.
List Your Goals
Write down positive goals that would help you achieve your ultimate health goals.
List Your WHY for Making this Change to Eliminate Your Habit
Listing your why is to understand your purpose, doing things intentionally, doing things for the right reason. This will also help towards your commitment to your positive change.
Find Healthy Substitutes for Routines
For example, if you are changing eating habits and you have identified a particularly difficult time of the day when eating habits are poor, create an activity, a new routine for that time.
Recruit Helpers for Support
Make contracts with a close friend or love ones to hold you accountable to the habit you will change. Enjoy small rewards when you achieve weekly goals to encourage continual motivation.
Be Aware of Individuals who Want to Sabotage Your Change
Communicate to them what you observe their behavior to be and explain how this is causing a hinderance in your progress of achieving your goal.
Allow Room for Lapses
Adopt the more helpful attitude of evaluating your progress and accepting relapses, and you will find yourself reaching many of your goals.
