You can be famous by doing something first or doing something the best.
You can be famous locally if you are better than average and globally if you are superb, but to be really famous, you have to be the first or the best.
Being first is usually easier than being the best, but also a lot of first timers do not become famous.
Being the best is really hard, but if you are the best, you will be definitely famous.
So, in the industry, in which you want to become famous, is it easier to come up with new things or to be better than the rest?
Whichever is easier is the winning strategy to fame.
