alt Hacker NewsMike Acton talks about deliberate practice in programming exactly this way. Every day start with a blank sheet and try to build something for an hour (his example is Astroids). Next day, start again and get a little further. Eventually you'll be able to build the whole thing in an hour.
I am not a programmer, so I did not know the name. But I just looked him up, and I can see why he is a legend.
His philosophy—stripping away the unnecessary to focus on the reality (data/hardware)—resonates deeply with me. The practice you described (building from scratch daily) is exactly the "Tea Ceremony" of the digital age. It is not about the tea (the result), but about the procedure (the internalization).
Thank you for introducing me to such a Master.
