I am my own house of record, I try to keep as much as humanly possible not throwing out the baby with the bath water. Sometimes there is little details you can go back to that were right on target and you did not know it at the time and also have new insight to old information, this helps to accelerate the learning process greatly. I only toss out that which I have combed over carefully to discover absolutely no further value.

Yes, having and hearing of successes are quite the motivator, especially when one is having a mental block.
