Here’s a first try on the importance of fundamentals in learning.
Imagine you are holding a long stick – better yet, a sword or lightsaber – representing your ability to make a difference in the world.
The far end of the stick is the part that you’ll make the greatest impact with. It moves fastest, reaches furthest, hits hardest.
But it’s useless if you don’t know who or what you’re fighting for (and/or against).
And everything the end of the sword does depends on what happens at the handle. You need a good grip, and the part closest to the handle needs to be – I think – the strongest part of the sword (armourers?).
A small change in the person holding the sword, a small movement of the hilt, makes a huge difference to what happens at the pointy end.
The rest of the sword is just an amplifier.
