Here are the cards I am targeting in 2017, along with runners-up that I will chase (just not as hard/expensive):
Mickey Mantle 1956 Topps #135:
Runner-up: Mickey Mantle 1965 Topps #350
1956 Topps - Complete Set!
I am close enough to taste it. I have less than 50 cards remaining to complete the set, and most of them are commons or minor stars. I think I can finish the set this year, assuming I can find a Mantle in my price range!
Runner-up: Complete 1969 Topps Deckle Edge Insert set

Runner up: 1949 Leaf Satchel Paige
Ted Kluszewski 1957 Topps #165

1964 Topps Venezuela Set - add 50 cards towards completing set
My current progress on the Topps Venezuelan set of 1964 is 117 out of 370 - that's a shade over 30%. I would love to get closer to 50%, so my goal for 2017 is to get 50 more cards for the set - that would get to 45% complete, which is fairly ambitious considering I added ZERO new cards to this set in 2016...
Runner-up: Specifically the 1964 Topps Venezuelan League Leaders subset - Cards #1-12
Reduce and ORGANIZE!
Several other collectors have stated similar goals, to get their collections into a more organized and focused state. I have lots and lots of cards that frankly are not part of my future collecting plans. The only bummer is that most of them are not really appealing to anyone. My collection of Braves, Red Sox, Cubs, Dodgers, Blue Jays, and Pirates have been picked pretty clean through trades, most of what's left are those 80s and 90s junk wax that no team collector really needs anymore. There's a bit more variety for the other teams, but again, most of it is not anyone's first choice.
By the end of 2017, I would like to have a much better grasp of what exactly is in my collection, and what I have to offer to others in trade.
