Is everyone's salary different in SF? There are high and low, are there any opportunities for development and promotion?

Do I think the wages in every industry are the same? Is on their own:

Every industry has opportunities for promotion, and opportunities are for those who are prepared!

Every industry has skills, so we have to do what we do, love what we do, and every industry has an example.

I take pictures of children. I'm not used to contact with some babies every day. With more and more babies in contact, I fell in love with them, and slowly discovered many baby contact skills! All this should be thanks to facememo's children's photography, which gave me a platform to play myself.
