Sense restraint for the duration of each day, sutta reflection during the quiet times of day (not intensive intellectualism, just a relaxed reflection). Sense restraint in itself takes a lot of practice, but also sharpens your mind for meditation.
Then just plenty of practice: two hours a day, or about. In this case I don't think it need all be spent on your butt, but rather those two hours can be spent sitting, walking, washing the dishes, sweeping the floor, etc. Anything that is simple to which you can dedicate your attention as completely as you're able too.
I used to meditate at night, hoped up on tea - I'd spend some time meditating, some time cleaning the kitchen, some time walking back and forth, etc.. practice like this until you get where you think you want to be.
