Keep a log and make notes of what was done right and what wasn't. You;ll get there.
That's really good advice. I knew a retired research scientist who help me a lot in a former life. That was exactly his advice as well.
Building guitars is complex stuff for the average guy. Often the things we learn, or fail to learn, are repeated simply because we forget not THAT we did something...but WHY we did it. Once I started keeping a journal I started going from point A to point Z on a much more direct path. Plus...writing helps me solidify what I've learned and makes it much more unlikely I'll forget the lesson....but if I do forget....I have notes.

As an example. I've probably done a hundred finishing or pore filling tests on 3"x 8" panels by now. For every one of them I made notes that detailed every step I took to arrive at that result. Say what you want about my guitars...but the finishes were pretty well done from the start. Mainly though...confidence to go forward was established not by flailing away, trying things...but by establishing the hows and whys prior to undertaking the larger problem.
So my particular advice is:
1. Whenever possible, break guitar building down into smaller, more managable problems and tackle those one at a time.
2. Test and prove all your assumptions whenever possible on something other than your guitar.
3. Lacking a full understanding of something...be as certain as you can about the outcome of a procedure before you commit your guitar to it.
