Cooowwwl: I'll be searching for Ikigai. Thanks for this recommendation.
the 'japanese secret' reminded me of the word "Chindōgu" - in free format translation, this means "Japanese Art of inventing useless products" ... Made me laugh a lot when a Dutch show created a small section in their program like 3 decades ago. I started using this when I worked for an aircraft company in the 90s. We did research quite a bit, creating mechanical pieces. Much of them landed on the top of cupboards which I labelled with stickers "Chindōgu department". At first, our manager didn't know what it was but didn't ask. Until a moment he asked who put those stickers on and what it meant. So I explained resulting in him pulling his eyebrows so high up that it touched the sky high above our heads, and those stayed there for quite a considerable time. And then he nodded so hard his head almost fell off. He made some not recognisable sounds and - almost - ran out of our room.
Anyway my association with this Japanese Secret and seemingly I was ready to share this memory. BTW, I was known for this kind of thingies, that's why he reacted like he did and didn't say anything. I remember one day I was not at the office, and the stickers got removed. Colleagues told me it was our boss who had done that, but didn't dare to do this in my presence.
Anyway, I do hope you can get to some of the recommended books and you like what you gonna read and absorb. Well, you can always forget about the 'absorb' part, costs more energy than not to absorb 😆
