Your first 10000 photographs are your worst.
The renowned photographer is right in the sense that, the more you practice, the better results you’ll get. Although it’s not a linear progression, each photo you make will, in general, be better than the one you made before. There will be exceptions, and evolution has its ups and downs. But in the long run this theory holds true.
In his book “Outliers”, author Malcolm Gladwell tells us that it takes approximately ten thousand hours of deliberate practice until we reach mastery of a given activity. He provides several examples. One of those are the Beatles, who have performed about 10 000 hours in clubs in Hamburg, before reaching international success.
Along these 10 thousand hours, or 10 thousand clicks, you improve your photographic technique. As you master it, you stop consciously thinking about it, and it becomes an automatic act. This way, you will be able to focus on composition and on the act of capturing the “decisive moment”.
Another thing that will happen the more you practice, is that your style will begin to show. The onion starts peeling and, layer by layer, you start to discover your photographic voice, your way to see others and the world. And this is only achievable with time and practice.
