Something interesting I see more often than not when someone I know decides to try out vim:
They know I'm a vim user so they ask me for good tutorials and I tell them there are lots out there but they should start by running vimtutor (included with vim). Takes around 15-20 minutes to work through the interactive lessons and gives you all the basics of movement and editing.
A day or so later I ask how it's going and the answer is usually that they're struggling with vim, so I ask if they ran vimtutor. Usually nope, or they started it but quit after a minute or two.
Why would one switch to a tool with a different paradigm, ask for and get a tutorial recommendation, and then ignore the advice of spending less than 1/2 hour on a tutorial that ships with the tool? sigh
