How often should I practice Mindfulness to be effective?

There are two uses of the word mindfulness there, mindfulness as an end, which simply means being fully human or being fully ourselves when we are a mind, we are full. But also mindfulness as a device to get us to that end. And I think the answer to that second one is, I mean, the first one, we obviously want to be there, I certainly do all the time, and I'm not by any, any means. But the device, I think, as often as it works, if it's too often, if it becomes irksome, if it becomes boring, then either switch to other means to get there or do it less often. I mean, if it's not giving you energy, if it's not making you feel good, then you're probably doing it too much or using the wrong device. But there are so many different ways of getting there that find a way that works for you and at a pace that works for you. It's not going to work if this changes your life. I'm always a bit worried by people who get terribly evangelical about it, about how it's changed their life after being on a course for two weeks. I mean it's a lifetime journey and we just need to recognise that. And it will go at its own pace, it will go at the pace that's right for you if you're doing the right things.
