Your Grandpa is 100% correct. Nothing is more demotivating than a rusty pile of junk.

I would also add to that to break the project down into steps. Focus on one thing at a time until the task is complete before moving on to something else. Buy only the parts you need for the job at hand. I can't tell you how many dudes I see trying to "stock up" the parts they need before even starting the project. Lets face it, you ain't gonna finish it in a day/week/month, so what's the point of buying now in the hopes of installing later? Later never comes and you end up selling those parts for 1/2 what you paid for them.

One other thing: try to do one thing a day to your project, no matter how small. It keeps you motivated and before long you will see progress which only motivates you even more.
