Personally, I would say the best feature would be to think creatively and being able to think on your feet because you have to adjust quickly when a problem arises, so I think if a person cannot do that then it will be difficult for them to handle the stress. It is quite important to manage a lot of tasks at the same time, so if they get stressed just from that and cannot think of solutions on the spot it can cause issues. Project management is ensuring that things are set up correctly and executed perfectly, which probably never happens, so it will be on them to think ahead and plan for those problems or know of solutions swiftly. For many people it is easy to get overwhelmed and get stuck on a problem for too long, which makes it hard for the work to continue, so they need to think on their feet as soon as possible and ensure the barrier does not stay for a long period of time.
