I think one of the main reasons that old habits are hard to break is because we’re used to them. When you’ve been doing something for a long time whether it’s beneficial to your life or not, it can be difficult to just let it go.
Even if you know it’s not good for you, you get sucked into the feeling of familiarity and allow the habit to continue.
But, what if you forced yourself to change, what if you made a choice to do something different and uncomfortable? Doing that allows you to open yourself to the possibility of a new life where you do thing that align with the kind of person that you want to be, rather than contradict it.
Overcoming a habit that is hard to break is joyous because you know it wasn’t easy but you did it anyway.
