Pressure to get car done

I am absolutely THE WORST when it comes to putting pressure on myself to get **** done. I have to realize that I am not 35 or 40 anymore, but almost 60. My mind will not accept that fact, so I set goals for myself and get really frustrated if I don't reach them.
I had the shiny show car long ago, it was fun, but it was much more fun driving the wheels off it every chance I had. Now I have an ugly sack of **** that I just don't give a damn about, but I still haven't got it to the point where it's dependable enough to make it a daily beater, that's my goal for it now, otherwise I'll just sell it and get something else.
I have an original, low mileage, unrestored car that I enjoy driving, it's not fast by any stretch, but it is a comfortable and reliable car to drive. At this point that's all I really want, but I do have another project coming in a month or so, that will keep my mind occupied, I just have to remember to enjoy it and not be in a rush to get it done.
