Establishing new habits and routines is hard. It is common to feel some mental resistance when you try to take action on your new practice. When I talk with people about building a reading practice, they often comment that it is hard to focus and make progress on reading if they have not been doing it regularly. You have to put in extra effort in the beginning.
If you persevere the requirement to put in extra work will fade as you build new neurological pathways to automate your new habit. What I have found interesting is that as I have established a stronger reading practice, the neural pathways of my old habits have atrophied. While streaming shows for a few hours once felt calming and natural, I now find myself unsatisfied with the lack of focus and depth. Our bodies crave homeostasis and often resist change. We can use this fact to help boost our motivation to clear the initial high-effort hurdles necessary to establish a new habit. The payoff of easier execution awaits us as a prize for our efforts.
