Without a Rudder

Ever feel directionless?  Like you're floating?  Not in the "happy cloud" way, but in the "I don't know where I'm going and I don't have the energy to care" way?  I've kinda got that feeling right now.  Hence why the post-silence.  I don't feel drained or depressed.  I do plenty of things just fine, but it's not easy to gather motivation.  Offer me a choice and I don't really care- sometimes I'll pick one just to move forward, but I don't have a strong inclination towards... well... anything.  It's been long enough that I need to DO something to snap out of it, but what?

Have you ever been in this mood?  Any suggestions?
