The secret to success is granularity. Tonight, before you go to bed, write down a handful of things you will accomplish tomorrow. Don't go crazy; fill a post-it note with normal-sized text. Tomorrow, after you've woken up, accomplish something on that list. It will give you the strength to go after the rest of your goals. Tomorrow, when it's time for bed, look at what you've accomplished and what you have left to accomplish. Odds are you will have made a dent, no matter how tiny, on your "to do list." I built a car from the frame rails up. As you might imagine, the to-do list had obnoxiously impossible tasks on it like "design and install brake system." However, "design and install brake system" is a half dozen subtasks (purchase tubing, select master cylinder, rebuild front brakes, rebuild rear brakes, bend tubing, etc) and when you take on those subtasks with a realistic point of view, you will get through it.
