The answer is simple: If you don’t know what to be gritty at yet, you need to try lots of things—knowing you’ll quit most of them—to find the answer. Once you discover your focus, devote 5 to 10 percent of your time to little experiments to make sure you keep learning and growing. This gives you the best of both worlds. Use trying and quitting as a deliberate strategy to find out what is worth not quitting. You’re not being a total flake but someone who strategically tests the waters.
