I've heard that it takes 10 years to achieve true mastery of any craft. He said it took ten years to "become a success", but that isn't limited to just one company. Personally, I plan on trying and failing as many times as necessary over the next 10 years until I get to be really good.

10 years to achieve true mastery? Sounds about right. I've also often said it takes 3 years to "get dangerous," in both senses. My data is from studying and teaching music.

On an even shorter time frame: once you get to the point that you're enjoying what you're doing, the only one who can stop you is yourself.
