Couldn't agree more, working on the truck is great therapy. Its important to keep an eye on that last part "move closer to the finish" else you end up working just to have something to do and finishing is no longer the goal. I have a 64 El Camino that was 3-4 months away from being finished for years cause I kept finding new mods to make (it was fun). Then I changed jobs, moved and put it on hold for a few years. Then along came the Suburban. Did I mention my wife bought the Suburban and supports all these (bad?) habits.
So I set goals: make the Burb watertight, make it run (and stop), then make it street legal. After all that, think about the mods and fun stuff but keep it on the road so we can enjoy it.
