I think you could just as well make the opposite argument: a retreat can be an easier way to get started, because it takes you away from your normal, everyday surroundings, and by really making it the main focus, and purpose of this time, it becomes easier to do, rather than to try and squeeze it into your existing schedule. There's a beautiful meditation retreat in Northern Thailand http://www.wetours.com/meditation-retreat-in-northern-thaila... (relatively meaning: get up early, no meals after lunch, very regimented day... but nobody will give you evil eyes and the people - especially the head monk - are very relaxed, easy going and have a great sense of humor). Not saying one way is better than the other, just that both are feasible choices :)
