There are 3 things I remember always when working.
1) Critical thinking and calm under pressure. When Under pressure the important thing is to always never panic, instead asses the situation and think of solutions and how to make things better to not fold/ mess up a situation. This is where Critical thinking comes into play and with that you have more clear ideas on how to solve situations and your problem solving abilities are more affective.
2) Communication and proper team work. Communication is one of the most important factors when working, it determines your/company/platforms success. With poor communication comes terrible team work. Team work is very important because work management can be easier and more efficient to solve. The worst thing you could do is not be a team player, and being a good team player has a factor of good communication.
3) Snowball effect. This is the worst situation to happen, especially in a place of work. A snow ball effect is much like a domino effect, where having one problem/situation that goes unsolved can ripple into many more problems. The most important thing is to take care of your tasks at hand and if a situation occurs where you have multiple tasks that require more then your current problem solving abilities, then communicate with your team or manger so a snow ball affect does not occur.
