My guess is that he, the magician, is stuck in a rut in life, not knowing where to go or what to do. Or maybe it's about a relationship that wasn't going too well, so he makes it disappear by ending it...? Maybe he "shakes" from being nervous or regretting his decision of ending the relationship. This is why "he sweats the most" and now he's a "shaking hand without a plan."
