Hi!
Actually, caring for my dwarves has allowed me to stick with the game. Their personalities and the creativity when making art/engravings is a major motivator for me.
Getting a fortress that live through two years without major loss of life is actually already a small land mark on your road to success with the game. So, you are not that of a newbie anymore, I think. Back in the 2D version, I went through hell trying to get my dwarves to survive (3D's surface farming made those days seem like a distant nightmare).
As for where to go from now on, that is really up to you.
One thing for excitement are the history projects I like to do:
First, I generate a world with relatively large forests and a lot of civilizations going through at least the 1050 years of generation. I have history hidden in that world and no culling of historic persons (and the init options set that history is shown for fortress engravings).
Then, when I embark, I choose a site within a large named region containing preferably settlements of mutually hostile races (it helps if you saw the conquests during world gen).
Then, I create my standard fortress (surrounded by wall and traps) and start engraving the floors and walls. The trick here is: The dwarves will occasionally engrave scenes from the history of the region the fortress is located in. So, if you are in a forest that has seen humans fighting elves, you will get engravings showing single incidents from that - besides scenes from battles with bears and the like. It can get very interesting when you get a series of engravings featuring the same named monster (I think had something with a couple of bears and also a troll or some such) in one fortress. Since history is hidden, you don't know what exactly to expect - so each engraving has the potential for new discoveries.
Well, that is my suggestion for the day.
