This is true, though there's always room to dive into new areas -- the corollary to 'keep on learning' is 'keep on improving.'   Nobody can be everything all at once, and sometimes making a choice to do one thing neglects another. But sometimes we keep pursuing the same things because we enjoy it, so it's a decision to drop the older thing in favor of the new, too.
