These are really good ideas, I am impressed.
Like Sweet2th and KC butch, I also did a pretty complete overhaul of my physical life. It has prompted me to continue to wanting to seek more changes along these lines which is why I am getting ideas from folks here.
Agreeing with MerryFairy on the importance of self care, and with Hollylane's suggestion for a nature break at regular intervals.
IslandScout, I do the exact same thing with food preparation. Even though I cook for one, you would think it was for ten. I love being able to open the fridge at anytime and know that there will be several very tasty and good for me choices available. It really reinforces healthy choices. I also like making big batches of soup and freezing the extra. That way even if I don't have the time to shop for a while I know it is there and always have a backup plan.
Corkey, knowing yourself is probably one of the healthiest things a person can do for themselves.
Brock, kudos on the apple.
