New habits take time to stick. Forgive yourself if you get thrown off a new routine when traveling. When big, unexpected life stuff arises, your new lifestyle becomes unsteady quickly.
Your new habits and routines take a while to fully embed and become not “new” anymore but really part of you. Until then, they are fragile and vulnerable to changing circumstances. When you are in a controlled, predictable, and familiar environment, your new things is easier to practice ever day.
But habits don’t exist in a vacuum. As soon as life shifts its circumstances, your new practice loses it’s tenuous grip.
So, practice it more. Practice it in changing environs and situations. Add a hefty dose of confident patience and kind persistence.
When it becomes deeply rooted, it’s much harder to shake loose.
