OK, this is my last try at it. 

Yes, you need a "good eye".  None of the books that I suggested to you deal with that topic.  That's something that I think you have to have a least a little of to start with as a talent, not something that can be built entirely from scratch.  Someone who has no talent can take all the classes in the world and get no where, that's correct.  We'll assume for argument purposes that you have at least a little talent in this field.

However, you're talking about doing this as a CAREER.  A BUSINESS.  You need to learn how the business end of this works, because you can take the prettiest hobby pictures ever, and still not be able to market them. And I'm not suggesting you go out and buy a book reviewed by no one.  I'm suggesting you go look up these books (perhaps at a library) and check them out yourself and see if they're worth anything to you or not.

And you are correct, I haven't been a travel photographer.  My parents however ran a photography business for more than a decade.  There is a lot more to it than just taking pretty pictures.  Even within professional photography, travel photography is a tiny little niche.  You're not going to find someone from such an obscure niche field on here.  You need to hunt those people up live and locally.  Even then, you may have a fair amount of difficulty because these people work freelance.  They're not sitting around somewhere in a bunch that makes them easy to find.  And no, there are not a lot of them because this is not a profitable field except for a very rare few.  An average person probably does have a better chance of being an actor that can pay their rent than they do of traveling the world and selling enough pictures to make a living.  At least being an actor does not involve thousands of dollars of travel money to pay off before you can see a profit.

So, back to my original point. Get off your duff and do some real research if you really want to make this happen.  Talk to the photography instructor at the local college and pick his brain for ideas.  Go to the bookstore or library and see what you can find that would be useful.  Take a class that explores the SALES of photography so that you understand what buyers are looking for.  Go to galleries doing exhibits of travel and landscape photography and talk to the artists and to the gallery staff.  Learn the technical end of photography so that you really understand it and can master your craft.  Call someone who works for a major firm that provides stock photography images for use.  See if some of those large companies might not even have submission guidelines posted on their webpages.  Get some objective opinions from people with some expertise about whether you even have any talent.

It is great to be creative, but you need to apply a tiny bit of pragmatism in order not to end up a bum (unless of course you've got a healthy trust fund to fall back on).

Good luck!
