Your plan looks sound. I tend to think along "Moses lines", you know, seven fat cows, seven skinny cows. It seems to be the way my life has played over the last 50 odd yrs. There are periods of scarcity and periods of good fortune, and I've been through a couple of cycles, prepare for the former while living through the latter and aim to achieve escape velocity at some point. Oh!, and enjoy both equally.
Great read, loving your content
