Try, Attempt
If you want to say something at a ceremony for construction workers you're going to have to try really hard. Construction is loud, so if you want to be heard you have to attempt to be louder than the drilling and smashing and digging and handing out of awards.
Try to imagine trying this hard to be heard. The construction workers are all screaming at each other with ease. It's so hard for you to try and keep up with their volume!

You try to get their attention the only way you know how, by lifting a sheep (し) above your head. The sheep baas and suddenly everything is silent, all eyes are on you. Well, they're on the sheep.
Huh. You should have thought to try this sheep technique earlier.
