In one sentence, describe what the following article is about:

If you want to make sure you are presentable, the mirror will tell you. If your hair looks good, your face looks good, and your clothes are situated like you want, then you are ready. You might need to give yourself a little boost to rise to the occasion of facing the crowd. Try some positive self-talk and say, "Okay, you've got this. You are going to hold it together. We are moving on." The feelings of whatever it was that made you cry might return to upset you again. If you start to feel emotional, stop yourself and substitute a positive thought. Pick a subject matter that is not closely related to the reason you are crying. The goal is to refocus your attention away from issue at hand. Tell yourself, "You are going to think about something positive like how much you love going to the beach. Yes, that is what you are focusing on now." Think about a project you are working on. Make a mental list of the steps you need to take and when you will get them accomplished. Imagine how happy you will be when it is complete. This will carry you out of the emotional darkness you might be feeling. You may not be an actor, but your body doesn't know that. The power of suggestion can be very effective. As you enter the crowd, perk up, smile and tell yourself, "You are feeling good and you are happy." Send yourself on your way filled with positive thoughts.

Summary:
Check yourself in the mirror. Tell yourself you're okay. Focus on something positive. Act like you are happy until it passes.
