That happens sometimes. Do you play an instrument, draw or write or anything? If not, there's always something else I do. Two things actually: First one, I drive with the radio blaring (running/walking in my neighborhood isn't really safe). Second one, I blast the music in my ears or house and get lost in it. I'll full on air play drums or guitar just for the sake of releasing the music's energy. Working out is good too, along with bouncing a tennis ball around and sometimes just nervous cleaning.
