Yeah, Right Effort is crucial. I had to relearn my understanding of effort when I first visited the hermitage where, unlike Goenka courses, there wasn't any timetable or instructions or rules apart from the sila and the serving of breakfast to the Bhante. Until then, my effort had been guided by the timetable of the courses. But at the hermitage, I had to relearn what 'Right Effort' means--I had to start by learning not to expect certain results or expect to sit X number of hours by X number of days. This is not to say that Goenka courses are bad--far from it: the timetable structuring the course and the discipline needed to complete a course are invaluable.
So I would add to that: if not for the first few years where I sat a full ten-days retreat annually as well as give service in ten-days and sit/serve in three-days retreats, I probably wouldn't be able to ease into meditation as easily as I do now. In the past six-eight months, I haven't been sitting daily. I'm slightly disappointed but at the same time not upset about it as such, because as I've mentioned before I've learnt to accept that one's life-practice changes over time in response to life situations. But I find that when I do meditate (average of four days a week?), I ease into it quite readily. When I say 'ease into it', it is not a matter of how deep or how concentrated I get. Maybe sometimes I do, I dunno.... by 'ease' I mean to say that I simply sit. However long I sit, however I feel (settled or scattered), I just sit and when the time is up, I stop. I don't dwell on it too much. This is something I had to learn of course, but that initial period of sustained effort and discipline played a big part I think. Perhaps for others the effort and discipline could be cultivated with other means, like dana/service for instance. But for me, the best way to cultivate effort is to pluck myself out of my comfort zone--the change of environment alone is a huge challenge in itself!
