What do I have to do?

Alright... advice please!

  I was told by a reliable source (who will remain unknown) about a year ago that writing will never be more than a hobby or release for me. Disappointed and hard headed, I decided to ignore this reliable source and continue to put my writing out there in hopes of finding some sort of work. I never have liked people telling me what I should or shouldn't do! I would love to prove this source wrong and become a famous writer, but I haven't had much luck.

  So far I've...
*Started this blog and advertised it every way I can.
*Made my own Facebook page and joined a couple blogging networks (Blogher)
*Called every magazine in existence just for them to tell me no.
*Called every newspaper in Texas, but they all seem to have an abundance of writers already.
*Emailed online websites asking to write for their newsletters, but I am ignored.
*Contacted many websites like Freelance.com to bid on jobs just to be turned down.
*I've even called an infomercial for writing medical reports online, but it turned out to be a scam.

  I do understand that it takes a long time to establish yourself as a writer before it can be a full-time (dream) job. Right now, I'm trying to get my name out there and make a little money while I'm at it. Could this source actually be correct? What the hell am I not doing?
See... advice is much needed!
