About
Researchers (Bloom (1985), Bryan & Harter (1899), Hayes (1989), Simmon & Chase (1973)) have shown it takes about ten years to develop expertise in any of a wide variety of areas (10 000 hour rules)
What a terrible advice. You will never learn as much as when implementing things. Otherwise you never go beyond abstractions’ demo use case.
