I was already vimming efficiently because I chose to ignore all those poorly written and factually wrong "tutorials" written by over-excited but under-experimented newbies. Instead, I followed the often overlooked built-in user manual, which taught me everything I needed in the most gentle and iterative way possible.
Vim is one of those tools where a couple of months of proper studying and deliberate practice puts you in a better place than 10 or 20 years of random fiddling.
