I think this is unhealthy self-handicapping. Your "flow" is just habits, things you've taught yourself to do. You weren't born with the ability to use either a keyboard or a mouse, there is no "natural" or "intuitive" way to operate a computer. It's all 100% learned behaviors that can be altered.
> there is "natural" or "intuitive"
Your argument is sound but this overstates your case a bit. There's a reason we don't type with our toes.
>Your "flow" is just habits, things you've taught yourself to do
By this logic a person who were comfortable with mouse should never grow to like VIM.

Fundamentally a computer is something that execute instructions. It is pretty poor interface to pick instructions from 100 options using a mouse as opposed to type it using a keyboard. A mouse hides the power of the computer behind a set of fixed clickable options. That is a pretty poor interface.
