I really like the aspect of focusing on more to stop overthinking. It's counter-intuitive but I also find it works wonders. When I first started meditating my head was too much of a mess to find the empty spaces, so I needed extra to focus on to achieve any sort of focus at all- exactly as your post describes! My route was through Tai Chi.
My blog is focused on meditations as well, feel free to check it out and follow if it interests you. Thanks for the post!
