This is a good example of why building a model is a good mental exercise. It will improve your ability to foresee problems, to visualize steps needed to take to have a desired outcome, to exercise judgement when dealing with imperfections, to improve your focus on completing the simple tasks, to better learn how to prevent the simple tasks from becoming more work than they should be. It's all mental gymnastics and even some kits no matter how well they are done require some problem solving. As you gain experience as a kit builder, you'll come up with your own favorite ways of handling some details in the kit that look like trouble. There is a certain level of perfection that you want to strive for, but it's nowhere near that of a watch maker. With the interlocking parts of today's kits that can be assembled in stages dry, it's never been easier to avoid gluing yourself into a corner.
