"Mr. Owl, how many licks does it take to reach the center of a totsie roll totsie pop?"
Much like knitting a sweater - to me! The world may never know - for that matter, I may never know! I loose track.
My problem is that I start out seriously excited the first time that I make a pattern and I work on it exclusively. If I make the same thing again (usually done at someone's request) I'm not quite so excited. That's when I'll switch back and forth between a couple of projects and loose track of how long I've been working on that sweater.
Another factor is size and pattern. My nephew's hoodie just flew on the needles. The cable patterned sweater-type thing that I'm doing now is much slower - I have to pay attention to the spacing of the cables and front and back and all that plus it's much bigger.
Don't stress about the time factor - try to enjoy the process! The only reason that I ever worry about how long something is taking is the deadline - birthday gift, Christmas gift, whatever gift! I do sometimes complain... "this is taking me forever! Will I ever finish it?"

But I don't worry that I'm knitting slower that I "should" be.
Plus... my DH said something to me once that really helped put it all into perspective: "You started knitting because it was fun, right? If you start stressing, it takes all the fun out of it so why do it?" He was right. I knit because I love to knit! :XX: I'll pick something else to stress over. Like finding a new place to hide my yarn stash! That's stressful! :rofling:
