Day 3 for me, WhyNot, and I'll be 41 in a month. Sounds like we're in a similar place. Like you I was working long hours to bank money up to a couple years ago, and then something shifted in me emotionally and spiritually. An inner voice asked, "How much is enough, and how exactly will I know that?" Turns out that happens to some people as they approach midlife. We literally shift from needing Achievement to Purpose (from a book called The Shift). Not saying that's exactly your case - only you know you. But that's what came to my mind.
I spoiled myself with junk food the past couple days and had bad dreams last night. I'm resolved to get back to cleaner eating today as an investment in this whole new life. Good thoughts ---> good food ---> good sleep/dreams ---> wake up with better thoughts --->... Seems to work for me (as long as I stick to it
)
Good luck!!!
