Don't look at the size of the whole project. Concentrate on what is next. I tend to get overwhelmed if I look at all I have left to do. Don't push yourself to hard. You will be surprised how much can get done in short spurts over time. I try to do a little something each day. Some days I do a bunch and some days not so much. The time line here is it will be finished when I get finished with it. Take photos so you can see how far you have come. It helps me to look at my progress from time to time. Other people's trucks are a good motivation car shows are good for a few days of productive work. Feel the force Luke. Draw your strength from the users of this site. It will get done.
