When I have limited amount of time even if it's more than enough I get stressed. When I'm on a job I have time to think about the problem, come up a rough solution in my head then start coding. If I have a hard limit I don't think that much because what if I don't have enough time to write it down? In the sort thinking phase I came up with a subpar architecture, but even if I have an extra half hour in the endI can't really change it or worst You cant finish it because I didn't think of an edge case.
