1. The "But I Love It" Mistake

Just because you admire something doesn't mean it's your purpose. Don't let yourself be distracted by something that should be a hobby. If you, like me, enjoy music, that doesn't necessarily mean you should be the one directing the song. Buy some CDs or enjoy music on your headset, just don't let it take your focus.
2. The "But That Drives Me Crazy" Mistake

Other people might not even be bothered by these things, but your inability to put up with anything less than excellence means that you have an interest there. You need to recognize, "This is an area I have passion about."
3. The "But My Dad Told Me to..." Mistake

This happened to me. My father owned a janitorial service, and it was his dream for us to own another family business together. As an adult, my brother started a windows-and-siding company and invited me to be a part of the it, but when I tried to twist myself into what my family wanted me to be, the business ultimately failed. I had substituted everyone's happiness for my own, trying to live up to my brother's dreams because I loved him and trying to live up to my father's expectations. But in reality, my purpose was in a completely different arena than anything they could have imagined.
This happens to so many of us. Every day at work, you might be like Jonah in the story in Bible, right when the ship hits a storm. Jonah knew, "I'm really going in the wrong direction. I'm going into the mouth of a whale." You know the exact same thing. You have to have the courage to withstand other people's opinions and ideas and to flow into your own purpose.
4. The "Do Something—Anything" Mistake

Everything else in creation has a Sabbath—a winter, a season of not being fruitful. But we're afraid of this. Look at fruit trees: They give up the winter for the spring. It's not healthy for livestock to produce all year long. We're so busy spitting out project after project after project that we don't give ourselves a chance to heal and restore and reflect and really find our internal heartbeat.
It can be hard at first to identify that internal heartbeat, but recognizing it determines what will give you fulfillment and gratification. Think of it as an inward applause for every moment where you feel in harmony with yourself, and when you hear it—be it loud and clear or soft and slightly muffled—you'll know exactly what it is and what you're meant to do
