@GloHo You said it! It is a "fine line". Only you know what that is and what that looks like for you. We can over extend ourselves at times which makes it difficult. I believe we do it for "fear of missing out" so to speak. Meaning we try our best to find so much to look forward to and experience plus leave behind that it can be all consuming at times. I truly wonder how I every would have worked through all of this. I would have given it my best shot, that much I know. If I also know myself, I probably would have been in hospital because of it. So I am glad I retired.
Do what you can, when you can and enjoy. Take the time to slow down and smell the roses. We forget about that a lot or at least I do and I have to remind myself to do it.
I am looking forward to spring and seeing the new growth sprouting from the earth.
