#1. Be willing to make the most of a bad situation. Most of us do not willingly seek out change and transformation - we grudgingly accept it when forced upon us.
#2. Every job has sucky parts. Most people succeed because the joy they experience doing the parts of their job that they like makes up for the angst they experience doing the parts of their job that they hate. Based on experience, you've got to be able to like at least 60 to 70 percent of your job or you'll burn out.
#3. You still need a sense of purpose for doing what you love - you need a vision for how your work will make the world a better place. No vision / no purpose; no purpose / no passion.
#4. It's still going to take some hard work. Just loving what you do doesn't let you off the hook!
