Joking aside, if you're repeatedly making mistakes then there's a serious flaw in your marking-up and layout techniques.
Everyone knows about the traditional cabinet maker's squiggle signifying "reference face" and "reference edge", and the "cabinet maker's triangle" signifying how components are laid out, but that's only the start of it. You need an entire language of hieroglyphics to denote the orientation of components and joinery. Some workshops have their own complete system which they teach their apprentices, but most woodworkers develop their own personal code. In my workshop I use a system of squiggles that tells me how legs are to be arranged, if Dominos are to be machined on the sloppy or tight settings, which veneer faces are the "show" faces versus "glue" faces, what is the top left corners of panels in frame and panel work, which is the waste side of every cut line, etc, etc. In addition any project apart from the most banal will have a dimensioned plan and a cut list.
All this means I'm a bit slower in the early stages of a project, but I hardly ever make mistakes like the ones detailed in this post, and virtually every full time cabinet maker that I know takes a similar approach. Hard experience teaches that in woodwork the tortoise always beats the hare.
