Actually since this thread I've been doing 30-45 minutes a day as an experiment. I have done meditation before alone and with a group, but never to this extent. While it's far too early to comment on how it's going without bias, I can say I have noticed several personal improvements that I believe I can attribute to the meditation. These mostly stem from applying mindfulness to my everyday life, which seems to be different to your experiences, but then again it has only been 2 weeks.
So far I find it more than worth the time investment, and at this point the 45 minutes flys by.
Firstly, why do you think it's worth it and do you notice a substantial difference in your life when you stop for whatever reason?
Secondly every time I read something like this, or talk to people that meditate, it seems extremely unscientific and filled with subjective analysis. Can you point me to something that would convince me that it has real world benefits, past that of taking a nap, or stopping for 45 minutes to think about your day/life.
I've struggled to find a target market though. Would you mind sharing what your use case is? It would really help give me some direction.
