It may seem like rushing around is what's required to get everything done, but if you think things through, you'll realize that's not necessarily true. Keeping cool is going to save you much more time in the end so think long term. Relax, organize your mind, and give yourself the time you need to deal with these problems correctly. You'll soon see that they are neither as big nor as terrifying as you feared they would be. Elevating your adrenaline isn't wise right now.
