I don't look at life that way. You replace fear with confidence. I don't believe you can do anything if you let fear overtake you. Somewhere that treats the workers well and encourages that continued growth. That comes by virtue of what you do and how you feel about what you do.
True happiness lies in caring about other people.
You feel good about yourself for being in that area. Look at the long haul, rather than the short-term. Fields come and go. Continue to pursue what you like and increase your skills. You are more than the sum of your jobs.
