I had trouble getting started too....
I started by listening to the Small Universe meditation while I was lying in bed at bedtime. The next day, I felt inspired to listen to Small Universe during the day while I was sitting -- I did the 3 guided rounds, and then 2 more rounds self-guided.
Next, I started listening to the Self-Concentration meditation at bedtime. After a few days, I felt inspired to listen to Self-Concentration during the day while I was sitting. I was amazed, when I felt the emptiness during the music portion of the meditation!
Next, I decided to try 10 minutes of the Active Exercises in the morning. I really enjoy doing the Seven Steps (active exercise #7).
Once I started practicing, I enjoyed it and wanted to keep practicing.
So, just start easy, and you will probably want to practice more and more, like I did.
