The font is tiny and written for those under 40.
It seems to have been written for Millenials and Gen Z. This kind of information has been around since the 1960s, if not longer, but it's been packaged in a way to make it appealing to those who may be new to intentional living.
I find it hilarious when the under-40s evangelize over thrifting, recycling, repurposing, home gardens, crafting, etc. as if they were the first to live this way. I grew up with the original ecology flag and eating organic before organic was monetized.
It's a nice book, and there's a market for it. However, if it gets reprinted, make the text larger - it's impossible to read.
