For steady shots hand held, experience helps to keep it clean but I know image stabilizers can do a good job nowaday although you don't want to rely on it for a total steady shot. You would prefer a steadycam or a dolly. What is your camera ? if it's quite a big one, use easyrigs.
But you know, shaky footage isn't always ugly, it all depends on what you are shooting.
