In a survival situation, don’t necessarily worry about how long things will take. Provided you’ve stabilized your situation, you’ll most likely have plenty of idle time. Instead, try to think about how much daylight you have, and in that context, if you have enough “daylight time” to accomplish any tasks you need to complete before the sun goes down. Pay attention to the weather too – it will often determine what you can or cannot do in terms of tasks. Remember – prioritize and be organized. Conserve your energy and be efficient. Take your time. Do it right – do it once.
