What to do when the low hanging fruit is gone...
You have two options when the low hanging fruit is gone. You can play a new game or you can strive to become THE best.
If you play a new game, its possible to combine skills to become world class (think funny writer + good artist = amazing cartoonist). Or, you become a jack of all trades, master of none.
If you strive to become the best, you know that the best reap disproportionate awards. But, you're playing a very hard, very competitive game. You may lose.
There isn't a right answer. Just a right path for you, right now.
