I think you need a complete change in mindset, because you're just setting yourself up for failure. You shouldn't need to develop a habit like reading or exercise. If you don't truly want to do these things then you'll stick to your systematic habit for a few days and it'll fizzle out, then it's back to the drawing board. I've been walking/jogging a few miles a day for the last 5 years or so. Now it's part of my life…
There are techniques for training yourself to think differently about tasks though; Tony Robbins talks a lot about how to train yourself to have the positive associations that you choose, instead of the ones that your environment and upbringing bestowed on you[1]. Some of that reads a bit cultish but I think there's some good stuff in there.
