You might have a few ideas... Write them down.
Now, look at this list for a minute and chose the one you feel the most attracted to.
Next step, implement this new habit for a week and during that week change nothing else.
Your goal is that within a week, you feel comfortable enough with this new pattern and don't feel like you are forcing yourself.
The following week, do the same:
Select a new habit you want to change.
While maintaining the healthy habit of the previous week, implement this new one as well.

Can you imagine the impact?
Don't rush!
Take your time to really ground these new habits in your life.
To your power!
