I keep a log of what happens, it's fun to read and see the whacky adventures the different dwarves have been up to.
Then I thought it'd be fun to sketch the dwarves. So I did that too .. after I had sketched about 20 I noticed that in the current release everyone has the same hair and skin color plus there are quite few variations between dwarves. No one had an extraordinarily broad nose or extremely long hair, no one had straight or wavy hair ... but I wanted to keep drawing.
I have sketched over 130 dwarves. It took some creativity to make everyone look unique with the limitations I just mentioned, but it was fun! Since the game didn't throw me variations I put that in myself. "Neatly combed you say? okay i'll draw it like a lion's mane"
... and now, with four years worth of logged material and hundreds of dwarves on paper.. and with large families emerging I couldn't possibly abandon! The 26 children will grow up and marry eachother; can't wait to see the family trees!
It's a freezing desert I have embarked in and while it's supposed to be haunted there's barely any threats around. It is VERY calm.. the caverns don't contain much dangerous things at all... but I greatly enjoy it. I mine and build and mine and build and log and log and log ... and sketch.
The best part? I'm actually learning much about facial anatomy and I have noticed a significant improvement in non-DF related drawings i make. ... so. like. um.

think my point is that if you're commited to your fortress or something related to it you won't have the abandonment issue. This game is about building so ... build! Build something!
Look up some medieval castle or such in your area and try to duplicate it
