Good morning @Former-Member, @outlander @Shaz51 @Appleblossom
Super big thank you for your responses.
@outlander What you describe about taking your focus away from your own thoughts and emotions is definitely one aspect of mindfulness. Another way of being mindful is to make the thought or emotion the point of focus. That is, rather than focusing your attention on something other than the emotion, you super focus ON the emotion. I do this quite a bit when I am sitting with my big feelings. It's like...rather than avoiding the emotion by distraction etc. I hyper-focus on the emotion - the pain of it and other physical sensations such as tears on my face etc. We will be exploring this idea more over on the DBT thread.
It sucks that you were initially only taught about one way of being mindful (i.e. using the 5 senses). I think this is part of what I mean about it being tossed around as an idea without being well explained. I also totally hear you about being told that mindfulness is the solution to EVERYTHING. I REALLY hate that - it drives me nuts! It sounds like you started to get the hang of what it means to be mindful, once you discovered other ways to do it. 
@Nell I super like the definition you gave of focusing attention on what is happening at the present time without judgement
. I think part of what gets missed in explanations of mindfulness is that it's not like we try it two or three times and then hey presto, we can do mindfulness. I see mindfulness sort-of like me learning to play the violin. Can I play the violin right now? Yes I can, and I can play better than I could three years ago. Can I now tick violin-playing off my list as something I have learnt. Er...nope (just ask my neighbours!). I can play better than I could three years ago, but not nearly as well as I will be able to play in another three years if I keep practicing and working at it. Mindfulness is like that. It takes a LOT of practice and there really isn't any point at which we go "hey, I can do mindfulness now." It is definitely an ongoing process.
@Former-Member you sounded perfectly articulate to me.
I totally hear what you are saying about feeling unsafe practicing mindfulness with anyone else around. I have only just started doing this in the context of my yoga class. I still don't really like the bit at the start and end of the class where we lie down with eyes closed, but I can tolerate it enough to see it as a good chance to practice feeling ok in a situation where I don't entirely feel ok. But yep, I definitely wouldn't have been able to do this in years gone by - hence why it took me so long to psych myself up to go to a yoga class! I have no desire whatsoever to attend any sort of meditation class or anything like that.
In the DBT manual it talks about how participants in DBT groups should not feel compelled to close their eyes during any mindfulness exercises. It super sucks if you were in a group where eyes-closed was insisted on.
I think one of the things that makes me feel safe in my yoga class is that my teacher couldn't care less if someone sits upright with their eyes open when she asks people to lie down and close their eyes. I would definitely run a mile if anything was insisted on. And yes, I totally agree with you about how mindfulness is thrown around as "the" solution to everything - super unhelpful!
@Shaz51 I look forward to seeing you on the DBT thread. 
@Appleblossom It sounds like moving mindful practices such as tai chi and yoga work well for you? I definitely find yoga super helpful in managing my big feelings.
Well thank you again everybody for your thoughts. You have given me some ideas about what sorts of things it would be helpful to include when I'm writing about mindfulness on the DBT thread...which you are all super welcome to come and visit.
