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....
I like to say that "the biggest barrier to success is failure." In other words, the longer you let a goal go unrealized, the harder it becomes to start because your repeated failures build up into a mental obstacle.
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.
there is one point more important than these. when you try to avoid thinking about anything, naturally your /dev/random of a brain will present you with many thoughts inspite of your efforts. the most important point is to not get upset at yourself for not being able to achieve "no mind" instantly. getting upset with yourself leads to a negative feedback loop which completely undermines what you are engaging in.
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.
