If you put a free license on some of your photos and 145889 people
downloaded and shared it, you would have 145889 people knowing about
you, and knowing that you make great photos -> they may hire you.
Note that:
a) We're not saying you should publich *all* your work. If you have 20
photos of John Doe, you can publish one low-quality and sell the other 19.
b) People copying your photos will get even less profit, as they will
have to acknowledge you were the author (i assume at least a Attribution
License).
c) If your work is bad. There's very little licenses can do to make you
earn more money.
