Not being able to execute the ideas you have comes from a lack of fundamentals, but studying the fundamentals alone is often boring and difficult – a recipe for avoidance.

The argument I’ve been seeing lately is not that quality isn’t valuable, but that the mindset of producing few high quality things isn’t an efficient way to learn. It leads to a lot of wasted time polishing potential bad foundations when you could move on and try again. Rather, you should produce a lot so that you get quality through quantity.
