The Angels say that if you are happy, then you will be happy anywhere. They say that the sad part of life is most humans look to find happiness outside of themselves. The unhappy people look to find a person, or thing, or job, or location, that will make them happy.
The Angels say that the happiness, the joy of life, must come from within. Happiness is a choice, regardless of your circumstances.
