I do it very slowly, often over the course of weeks. If it’s something like a cooking project for example, I’ll spend one week gathering ingredients, typically one weekend experimenting, and another weekend on making a finished project. If it’s a craft project like the gas mask I’m working on, it might take me several months working a few hours a weekend at a time. I find the easiest way to avoid getting overwhelmed is to move at my own pace. I also allow myself to have different types of projects ongoing at once, but crucially only one of each type. In other words, I can have a computer project, a cooking project, and a craft project, but not three different cooking projects.
