Even with tools that seem reliable, you still have to account for unpredictability because deadlines, instructions, and human error all add variables. Things like last-minute clarification needs, internet issues, or miscommunication can affect the final outcome, so it’s smart to build a buffer and not assume everything will go perfectly. I’ve seen people rely entirely on external help and get stressed when something unexpected happens, so planning ahead, checking drafts, and leaving extra time always makes things smoother and reduces unnecessary pressure.
