On track to reach $300 in sales on KDP this month
If it happens it would be my best month in 5 years
The result of
1) Writing about what readers want, not what I want
2) Focusing only on self-publishing and no distractions
And listening to amazing people like @rocketshipalx 🚀

Thanks to everyone who gave me suggestions!

Earlier this month I published a new book
After the free promo sales dropped drastically
But now they are picking up in the last few days
I like this trend, it looks quite healthy

I thought I read everything Feynman wrote but I was wrong
In his Nobel lecture, I found this entertaining account of how he got the idea of the path integral into a conversation with Herbert Jehle while drinking beer at Princeton
The importance of drinking (and socializing)

Finally, snow!
I have been living in warm countries for 30+ years of my life and I realized I really enjoy cold and dry winters
I mostly feel awful in European cities like Milan in summer, with super high humidity and 35 degrees
Instead a walk in the park with -5 or -10 makes leaves me focused

Struggling to keep my focus, on thing trusting the process and hoping for the best
I launched my book at the end of November and it's been a little underwhelming so far, but I keep high hopes

I don't like the Copenhagen interpretation of Quantum Mechanics, but it's mostly a matter of taste, as with all the interpretations.
Among them, the only ones I like are the spontaneous collapse theories. Because they can be falsified and constrained by experiments.
Unlike MWI
