I'm finding that Fro Knows Photo is a really great resource for up and coming photographers. Actually, you could probably apply a lot of the principles to any form of business...
He's a bit of a silly guy, but the results do the talking. Jared is an amazing photographer that has some really great insight into "the biz".
Recently he started up a podcast called RAW Talk. Er, about 6 months ago. I'm just checking out the first episode now and it's really great. Candid, yet professional. Jared and his co-hosts are really open and honest and provide some really sound advice.
I highly suggest you check it out.
