Me, too.  I'm currently working on a pair of 1/72 Italian fighters, Italieri's Re 2001 Falco, and Airfix' Fiat G50.  I started them in June, I think, though I've probably spent no more than 8 hours total time on them.

My USS Pennsylvania build has been in progress since 2010,  I think, and same thing--probably about 12 hours total time so far, maybe a little more.  I have an Essex that I started back in 2006 or 2007, can't remember, but I think I've spent only about 4 hours total on it, so far (and it's only about 1/4 complete).

Well, it is a hobby, not a job, so I don't worry too much about my pace
