To last, to be great, you have to understand how to rest. Not just rest, but relax, too, have fun too. (After all, what kind of success is it if you can never lay it down?) The most surefire way to make yourself more fragile, to cut your career short, is to be undisciplined about rest and recovery, to push yourself too hard, too fast, to overtrain and to pursue the false economy of overwork. Manage the load.
