If you know, why don't you solve the issue?

I also know that I should arrange my diet to have more fruits and vegetables than it currently does. However, after a few decades of doing things one way which isn't optimal, but is good enough to get the job done, simply "deciding" to do things a different way isn't enough to alter all the various unconscious mental sub-units whose interactions lead to the behaviour in question.

I bought a pumpkin pie yesterday instead of a box of cookies. I've started using beta-readers. Neither one is a perfect solution - but each is a single-step improvement over the previous situation, a step that is within the range of behaviours I can get my unconscious processes to actually accomplish, and hopefully, isn't going to be the only step.
