Random thoughts... I have no idea who Ryan Tedder is... I've never sold a song, and I don't know anybody making a living solely from songwriting...
Given that you already have terrific songs, you have to get the attention of people who can put those songs in a position to make money, and that's getting harder all the time. Probably the best bet for a non-performing songwriter is to network as much as possible with up-and-coming performers, do what you can to help them break thru, and any attention they get will reflect favorably on your songs. Also, look for opportunities to co-write with other writers. A lot of the business is face-to-face, personal relationships.
It's probably helpful to focus on a genre: pop, country, R&B... because styles have specific characteristics, and it's hard to be authentic without really getting deep in a style, but don't cut yourself off from opportunities outside your comfort zone.
