Lacking the mojo

I cannot find my sock knitting mojo. I have had the same pair on the needles for what seems like forever (really 3 weeks) but I haven't even knit half way down the cuff. I only have 2 things going now so I am forcing myself to get knitting on them but I feel like a 12 yo who was just told to clean his room. Mayeb the more I knit, the more mojo I will get back.
