This is going to sound so lame, but... time. My goal was to do it the "right way" and thus I wanted to get through these: http://www.audiodharma.org/series/1/talk/1762/ before I started. Perhaps I should just read something and jump in....
Turning something into a habit takes a lot of repetition so it's better to just get started with a modest objective so you can create a pattern of success.
They're only about an hour to 1.5 hours long, and there's only 6 of them. They are supposed to be spread over a 6 week period. So every week for six weeks, you need to find an hour to spend listening to the talk for that week.
You will be meditating during part of the talk. Other days, you will meditate 20-30 minutes. This is not a large time commitment, and since you're on HN, I'm guessing you'd be able to manage.
Good luck! The first two talks have been pretty nice so far.
You don't need to know more to get started.
I find a helpful illustration is a glass of champagne. the bubbles will keep appearing. note them, and allow them to float to the top, and dissipate. do not get upset with yourself when you find that they keep coming.
