About time for mindfulness to actually be a thing. Waiting for a time where people are at least exposed to the idea of mindfulness, whether they continue to practice it, is their choice. A subject in school is the best way to achieve this.
For adults, if one thinks that they are already super happy and self-realised, it still makes sense to try out the techniques of mindfulness just with a consideration that they "could" be even more so. They "could" be missing an entirely different dimension.
Personal experience:
Up till the age of 21, I was enjoying my life, doing well, fooling myself that I am the happiest I can be. That's when I took this course in IIT Madras called Self Awareness [1]. I had taken it because people said they always give good grades. The course caused a massive self-discovery for me. It was all and all about mindfulness. The teachings were mainly from the books: `Siddhartha` [2], `The power of now` [3] and `Stop sleep walking through life` [4]. They introduced us to relaxing exercises, meditation and breathing techniques along with some ideas to watch yourself while you are getting emotionally vulnerable. Briefly, the course was about being conscious of your existence, about feeling one with the present and about figuring yourself out for real. It has been 4 years since and I can clearly see that I am a different person, I have much less fights, I am rarely depressed, I handle criticism much better, I am much more productive in my work and most important of all, I have the clarity about who I am.
Sucks to think that I wouldn't have known (never mind achieved) all this if it weren't for a mindfulness course. Props to the schools in England for this initiative.
