My first time using a circular saw I white-knuckled it so hard I nearly threw the thing across the garage. @the_derek is right, you really do have to chill out and let the tool do the work. I mean, I was fighting it like it was actively trying to hurt me, which maybe it was. Took a bent cut line and a lot of deep breaths to figure that one out.

Yeah, a cheap dial indicator saved me from guessing on wheel bearings too.
