As long as you aren't grinding any gears, its not doing anything bad to your truck at all. Once I was out on a trip going fourwheeling, and I came to a stop light and pushed in the clutch and wham stuck to the floor. So I shut off the truck and rolled over to the side of the road, only to notice that my clutch linkage had vibrated and fell out. So I called my dad and asked him, and he said just come to a stop light and shut the truck off, then put it in creeper gear and start it up when the light goes green, will be a little jerky but wouldnt hurt anything, then just shift the gears normally using the RPM. I drove the rest of the way (another 40 miles) then back home later in the day, ( 140 miles) and it was easy as pie and didnt hurt anything. Sometimes I shift that way now, just becasue i am too lazy to push in the clutch, works both ways upshifting and downshifting. And yea, my buddy that drives semi truck only uses the clutch to pull out, and never again till he stops. Won't hurt a thing, and if you keep practicing, you will be ready if your clutch linkage falls out.
