Stuck in a Rut

Today I feel like i'm stuck.  I want to move forward, and I know I should, but i'm unable to.  I make some forward progress, but its like the mud is super sticky and rubbery, and yanks me back if I stop intentionally moving forward.  It's rather frusterating, because I get far far far far forward, then feel that maybe I can relax a bit (or I get tired) and VwaZingSNAP! I'm back in the rut...  Maybe its time to change the tires...
