Hello there @chappertron :)
Thank you very much for coming around.
I like the don't take yourself too seriously part of your rationale. However, in my opinion, I see thinking as a very good habit to nurture (not of the ruminative kind, though). I greatly believe that quality thinking plays a fundamental role in psychological well-being :)
I have seen Eckard Tolle's books, but never read any of them. The one that's always on display in Fnac (my favourite book shop) is the The Power of Now. You seem to recommend his writings? If so, I might add to my long list of books to read :D
