The really cool thing is - it doesn’t need to be easy, you don’t have to be ‘good’ at it in order to work. I highly recommend the ‘mindfulness for beginners’ course by Jeff Warren on the app Calm (30 times 10-12 minutes) If you prefer reading, he co-authored the book ‘meditation for fidgety skeptics’ which is also down to earth and humorous.  By the way, I’m in no way affiliated to him in any way, was just relieved to find someone with his style to ease me into it.
