- Always have a few directions you would like to go with your set, you never know what the crowd is gunna react to, so it's best to be prepared. - Watch your levels at all times. a good set can sometimes be as simple as playing it at the correct volume, you dont want to smash sound into the clubs limiters all night, especially on a hot night. - Step away from the decks once in a while and try and focus your attention on the ambience of the room, to see if it all sounds the way you'd like. Maybe the room has a real problem at around 100hZ, so you might need to back off the low's a bit. Or maybe your treble is really cutting through on a particular system. Either that or ask a friend to jsut walk around the room and give you an assessment of it.
