Focus on More At-Bats
In another great post by Marc Andreseen, he highlights some data to show:
Quality of output does not vary by age... which means, of course, that attempting to improve your batting average of hits versus misses is a waste of time as you progress through a creative career. Instead you should just focus on more at-bats -- more output. Think about that one.
So the morale is: just keep trying!
