How do you know if this is the case? Ask yourself these three questions: 1. Am I making progress? When you look in the rearview mirror, there should be a lot of landscape back there. If you’re still where you were a year ago, something is very wrong. 2. Am I fulfilled? After a hard day of doing what you’re doing, you should be able to hit the sack knowing you did your best and forgot the rest. 3. Am I still loving it—at least a little bit? Even if it’s a tough job, it shouldn’t tear you apart to the point that the rest of your life stinks.
