I've been meditating and doing a bit of mindfulness myself lately too.. always wanted to do it on my own as well. But now my group therapist came back after 4 meetings (havent had her as the group therapist, only did the intake with her) and she told she went to a mindfulness course and she wants to form a group.
I really hope it will start soon, cause i know that being in a group can sometimes amplify the results.
I have positive experience with it, oh yes! Plain and simple, it gives me the courage to be disciplined in my daily life. If i can dedicate 10-15 min every morning to a small meditation/mindfulness practice, it somehow helps me to stay focussed a lot better than if i dont do the practice.
I've been searching on and off for a good method, but to me http://learning.tergar.org/
works pretty good. If you create a free account, you get access to introductionairy videos which are told by a very funny monk. It gave me the confidence to start the practice, even though i lack concentration..
so far, so good.. perhaps you can give it a try too, this teaching is also buddhistic, but there are no strings attached..
