At what point do you pull the plug?

I have noticed that I go in cycles. Bicycles, A Bodies, engines, music, fishing, and hunting. Work was overwhelming and I had no time. Things just sat, and I was OK with that. I would get parts that I would want and could wait for. I am now retired, but I will not put any deadlines on myself. I just make a list, and work towards the end when you want. Another mistake people make is having to have the latest and greatest. You don't need to have a 360 or a stroker if you have a 273, or 318. You don't need aluminum heads or super parts to have a blast on the street. That is why we have Mopars. Do a descent job on what you have, get it going and enjoy it. On the other hand I have been getting rid of things I have no interest in. But I cannot imagine not having a 4 speed, HP V8 early Barracuda. If you don't have space that is another point. Only you know what to do.
