When starting to cook on my own, I always found it very stressful, because I felt you had to do so many things in parallel and then you look away for too long at the wrong time and something burned.

What helped me is reading the whole recipe very carefully and then prepare everything before actually starting to cook. Many recipes tell you something like “while x simmers, cut y / prepare z”. That’s fine, when you have developed a feeling for how long things take, but as a beginner, it’s better to do everything sequentially. It takes longer that way, but it makes it much less stressful and overwhelming.
