We all need a little motivation, no matter how long we've been here. I just got a copy of "The Spark" (found it at a used book store). It's what I needed to get re-motivated.
The whole idea is making this a life-style. Set small goals for yourself and as you achieve those, you'll gain confidence. I like Chris' idea that the building blocks of Spark are: focus, fitness, fire (you see possibilities, not problems), and positive force (share your energy and success with others).
Keep plugging away, new SP.
