I just have to say, I read mini fridge, then saw the photo and I immediately thought you must be some kind of crazy in the US if that's a mini fridge before I read the rest of the sentence haha
I also hate the ones about optimizing everything or being productive every second. If I need to optimize and use the time I spend on the toilet well, then something is wrong with society
Honestly, I hate self help books in general, they usually claim the secret to life is being organised, meditate, visualize stuff and sleep well. Gee, thanks, we know. I only read the ones people recommend over and over and I think I've come across this one a while ago and wasn't impressed either
