Most people like to get things done as efficiently and quickly as possible. However, as author Haruki Murakami points out, sometimes the fastest way to do something is to take your time to do it right.
This quote comes from Murakami's book What I Talk About When I Talk About Running. In context, Murakami is talking about learning how to swim properly when he was training for a triathlon, but the idea of taking your time to learn a new skill works for most things in life. Learning some things quickly is a handy talent to have, but you have to take your time to tighten the screws of each part if you want to tune that skill to the point where you're as efficient as possible.
