“There is a gap. That for the first couple of years, that you are making stuff, what you are making isn’t so good. It’s trying to be good, it has ambition to be good, but it’s not that good.” […]

“The most important, possible thing you could do is to do a lot of work. Do a huge volume of work. Because it’s only by actually going through a volume of work that you are actually going to catch up and close that gap.”

I agree with the sentiment.

The more work you do, the more of an expert you become.

And with expertise comes the ability to really make things happen.

And there is research to back it up:

"Some historical studies of patent records have in fact shown that overall productivity correlates with radical breakthroughs in science and technology, that sheer quantity ultimately leads to quality"

My childhood friend, Charles Steinhardt, said to me when we were 16, at Science Olympiad nationals, "Do one thing, and be the best in the world at that one thing. You don't need to be the best in the world in everything, but you can be the best in the world in one thing."

Alternatively, you can be really good at two things that in combination are rare.
