Walk loudly and carry a small stick.
After all, carrying a big stick gets tiring. It's much easier to do a lot of shouting than to do all that manual labor.
I recommend shouting whenever you get the opportunity. It makes a good impression on whomever you are shouting at.
And if you can't make a big impression, at least you'll have made a dashing attempt at breaking their eardrums...so it wasn't really a total waste of breath after all.
