A cycle to break, not lean into. Trust me, I've been there. I had the sort of brain that needed to be kept busy, because without it being busy I had to work out why I couldn't be bored. What was it about spending time with my Penguin-self that I didn't like. Now, I am happy to be bored. Sometimes I am busy, sometimes I am not - and I am much happier being by myself and flowing through life. If you have no momentum, enjoy the rest - that is what your life is telling you.
Don't mistake productivity for purpose - and if you've got time, look up the Chinese principle of Wu Wei - I found it a life-changing concept and have integrated it into all aspects of my life. :o)
