I think almost any job or profession needs coffee at some point. Unless you are able to stay awake and focus, you won’t need that caffeine. Occasionally you will encounter one of those days that you just can’t keep your eyes open. This is the time to get some coffee and hope that your boss won’t be asking what you did last night. Usually early morning before work is the best time to get a cup of coffee just in case your energy level is not sufficient enough to keep your awake and focus for the whole day work. But if you are the type of person who always has a cup of coffee every morning, sometimes a cup of coffee just might not enough.
