Yes just do it without knowing how to do it! That always works out well.

In software, where the consequences for initial failure are extremely minimal, sometimes it does actually work well.

But learning about, while possibly a prerequisite, still isn’t getting it done.

The point is: don’t stop at learning how to do the thing.

Actually do the thing.

So skip medical school and grab a scalpel and cut out brain tumours?

I don’t believe I ever said “don’t learn how to do the thing”.

But many learn how to do the thing, and still never do it.
