I’m about 3 days in and I’ve worked on about 10 projects so far. Something I was wondering about from the community is about time logged. So far certain projects do not take me very long(between 15-30min), and I’m not sure if I should spend more time on them or not. Moreover do people normally think through things while on a task and ultimately log more time than they should? Just a few questions that would be great if people could shed some light on them, thanks!
