CONSTRUCTION cluster

This week during my career exploration class we reasearched the "construction" cluster where I chose a taper and electrician which aren't my two dream jobs, but the description for an electrician is "fix, repair and replace electrical or oulets for homes and buisness, the "tapers job" seal joints between plasterboard or other wallboard to prepare wall surfaces for painting or papering. Now what does all of this mean to me? pretty much nothing I could care less about these careers but we NEED people to do them and if someone wants to do it, then by all means go for it.
