One of the things that I am interested in as a person, as a professional and as a scientist is meditation, especially mindfulness meditation. I've been involved in both researching MM outcomes and guiding MM sessions in novice groups, as personal development workshops mostly.
One of the things that I was most surprised about is how people often EITHER misinterpret the "be here & now" messages, artwork, videos, etc. promoted on social media, and the web in general, to be somehow related to spontaneity and extraversion, OR are just oversaturated with this very popular saying, that is becoming even more so. And they just don't really care about what it could really mean.
It's nice to see people really get the meaning of this message after only 10 minutes of MM. You can actually see it in their eyes, as they leave the room, that they finally understood the fact that their life is happening right now, as they step towards the exit and as they put their hands on the door handle.
Guess too much of something creates the opposite effect. People just shut down and ignore information. Give them some experience and they'll never forget it.
