Yep. The reason that you are going to be a good knife maker is because you are already well aware of what went right and what went wrong. You are honest with yourself. That's really all there is to it.
The real lightbulb moment for me was this: Instead of focusing on the finished knife, instead focus on the one step you are working on at a time. Break the knife down into elements. What is the desired shape? Start by making the absolute best profile you can make. Make the best, most accurate pin holes that you can. when you go to make the handle scales, make the best and most accurate (flat and square) handle scales that you can make. Then use your nearly perfect blade profile as a template to drill the most accurate, square pin holes in the scales.
You get the idea. Whatever step you are on, do the most accurate and perfect job that you can on that one step. There is no value in rushing through a step just to get to the next one. If you do that, you'll always have a piece of that knife that you could have done better, but it's too late. To Drew's point. While you focus on the step you are on, you also need to think two or three steps down the line. "Once I get this handle on, how am I going to hand sand this blade? I should do that before I put the handle on."
The other side of this coin is "the best you can do (at this point in time) is the best that you can do." Sure, we'd all love to turn out museum quality knives. But nobody starts out there. There will be times that you aren't 100% happy with a step that you're working on. You'll know that it doesn't meet the vision in your head, but you'll have no idea how to get from here to there. So in that case, you do the best you can and accept that there is a limitation here that you need to improve upon. This is also why we all need mentors. It's the greatest thing in the world when you can call somebody and say "Hey, I'm stuck. I'm trying to do "x" and I can't figure out how to do it." and get an answer on the spot that puts you in the right direction. Sometimes it's a method, sometimes it's a tool, and sometimes it's just more elbow grease.
Keep at it. You are off to a great start.
