Maintain your clarity of mind. There are forces in motion that are way larger than you, and they seem to be in operation in all areas of your life. You are not going to control them, but there are more and less appropriate responses. The more appropriate responses all begin with applied intelligence. Rather than being about how smart you are, this is about what you do with your information and your observations. It's about what information you use to inform the choices you make, and knowing when you must make those choices. I assure you, there will be moments when a decision seems too difficult, without enough time to think about it carefully. That is why you must be aware of your environment, prepare in advance to the extent that you can, and, most of all, know yourself. The sensation of time as pressure is something to consider. Rarely will any perceived shortage of time be as urgent as you think. What is vital is that you set a structure for time, and work with a plan at all times. Set a deadline for everything. If you have to make a decision, make an inquiry and determine how much time you reasonably have. What feels like you have an hour may turn out to be two days. What feels like forever may be one week. Clarity of mind translates to "Time is of the essence."
