Find your passion, then work will be easy! Or, as many a NextGen-ers have said, "If only someone would pay me to do what I am passionate about!"
The problem is, Ms. Millennial, next month your passion (about which you are convinced today) will have changed. Human trafficking will be out of vogue, and the pink-striped salamander will need saving.
Work is work. Sometimes it is inspired, but after the inspiration comes the perspiration. I have written many books, and I love the process... and I hate it. Sometimes it is like wading a swamp, other times like soaring with eagles. If passion--and, by that you mean, feeling constantly excited and uber amped--is your guiding light, you will end up chasing fireflies down a winding path that goes nowhere.
Purpose trumps passion; obedience is bigger than both.
