If you're like me you might love to solve problems, but get fatigued by the idea of never-ending problems.
But, the thing is, it's not like Groundhog Day. They're not the same problems. As you become more successful, generally speaking, you get given better problems.
Checkers becomes chess.
X's and O's becomes Battleship.
$100's becomes thousands.
Enjoy the problems of today, and when you finish them, get ready to embrace the problems of tomorrow.
