I think LearnVest is one of the best sites out there aimed at young women who want to understand money better.

They have a genius slideshow call 30 Bad Financial Habits to Drop By Age 30.

#10, Stop Asking Parents For Money is my favorite. If there is one issue I see a lot with women I know and around the way -- that bothers me more than anything -- it's how many still live off their parents. Even if it's just a credit card, it's inappropriate when someone is deep into their 20s and beyond. At the risk of sounding judgey, it's just lame. I don't understand how parents allow it when their kid should be a functioning member of society. Don't they feel like they've failed in some way?

...and now I'll get off my soapbox.
