You can study on the job. It's, in fact, the best way to study. Even if you're using technologies you already know, there's almost always something you can learn on the job. If not, switch to a job where you're not learning.

Also, achieving results is not done by working long hours. It's done by avoiding unnecessary work, by prioritizing. My experience, and that of others who work less than 40 hours a week, is that we become far more productive as we developed the relevant skills.
