Why friction is necessary for growth

If you're riding a bike up a hill, you can't go up without effort. But not all of your effort is actually moving you up the hill -- some of it is being lost in friction: inefficiencies in your muscles, friction in your gears and wheel and chain, wind resistance.

Similarly, you can't learn anything without effort; but it's often the case that effort you put in ends up wasted: if you're learning a language, time spent looking for content rather than studying content is friction; effort spent forcing yourself to read something that's too hard is effort you could have spent more profitably elsewhere.

Put that way, we should minimize friction, so that we can maximize the amount our effort goes towards actually growing.

It reminds me a bit of looking up coding solutions on StackOverflow back in the day. Yes, it was a slog and consumed valuable time. However, I always felt that I picked up all sorts of other valuable information reading a variety of possible solutions or spying a related but different problem and taking a moment to consider it.

It is similar to how I learned to play guitar. With no videos and very limited tablature, I had to learn songs by ear which was crazy inefficient. However, it trained my ear and kept me exploring the entire fretboard as I figured the song out. This ended up making me a much more complete guitarist.
