As with any project, that goes from concept, to completion, it is important to have a plan. By having a plan, you can keep moving toward your goal of completing the project, regardless of how ambitious the undertaking. If the goal is to keep the truck in service, during the process, breakdown the process into manageable tasks, that fit your time alotments, investment capabilities, skill set, tool availability, space and level of commitment. All of these elements have the capability of derailing a well-intentioned project. Commit your plan to paper...there is a tremendous sense of accomplishment, when you complete an item, mark it off the list and step back, to see your overall progress and persistence. I have found motivation to be greatly influenced by the notion, that you are gaining on the goal, whatever it is. Sometimes we have more time, than money or more "want-to", than "know-how", so with a plan, big or small, good things are possible.
