Problem: Article: A great way to change a habit is to replace it with something else. Smiling inappropriately is really just a habit, so you should be able to pick another behavior that you can do instead. Choose something simple that others are unlikely to notice, such as biting down on your tongue, rubbing your fingers together, or wiggling your toes. It's great if you can pick something that helps you deal with your feelings of discomfort. For example, if you smile when you feel under pressure, replacing the smile with silently taking three deep breaths can also help you calm down and relieve the pressure. Imagine that you're in a scenario where you might smile inappropriately. Imagine who you would be with and what they would do or say. As you do this, practice your replacement behavior while not smiling. If you feel comfortable, you can ask a friend or family member to role play with you and to pretend to be someone else so you can practice. Practice many times, until doing your replacement behavior instead of smiling becomes second nature. You may not be able to plan for this, since triggering situations tend to be unpredictable. However, you need to practice in real situations in order to fully develop your new habit. If you still smile, and it's not too embarrassing, you can say something like, "I'm sorry. I know it's inappropriate that I just smiled. It's something I'm working on. I'm not actually happy to hear the bad news." Continue to practice, both at home and with other people. You can replay a real-life scenario by yourself later, if you want to practice responding differently than you did. Not all replacement behaviors will work for you. If the one you chose isn't working, try a new one. Practice it at home and in real scenarios, too. A behavior may also involve saying affirmations or mantras to yourself. For example, you may need to tap your fingers together while also thinking to yourself, "I am sorry to hear what this person is going through. It's difficult for them."
Summary: Choose a replacement behavior. Practice replacing a smile with the new behavior by yourself. Try the replacement behavior in a real scenario. Choose a different behavior if you need to.

Problem: Article: About half an hour prior to takeoff, the gate attendant will announce the boarding time. Boarding is done in sections, either by group/sections (designated with a letter) or by rows/seats. Check your boarding pass to see if you belong to a group, and if not, wait for your row or a section of rows to be called. First class always boards the plane first, followed by business class and people with disabilities or infants. Although it is not always the case, it may be beneficial to try to snag a place in line early on so that there is still room in the overhead bins for your luggage. Otherwise, if storage space runs out your bags will have to be checked. After waiting in line for boarding, there will be a gate attendant next to the entrance waiting to check your boarding pass. If you are flying nationally, hand your boarding pass to the gate attendant who will scan your boarding pass in (by placing it down on the terminal), but you will not need your ID out at this point. If you are flying internationally, you will need to show your passport again at this point. Keep your boarding pass out after having it checked, as you may need to show it to an additional flight attendant on the plane. While most hallways are short, there are some gates who may have line hallways much longer and curvier than others. There is typically a buildup of passengers after the boarding pass check, so you may have to wait in line again before boarding the plane. Check your seat to make sure you are headed in the right direction, and keep a lookout for your row number. If you need help finding your seat, ask others around which seats are for which row and later which seat letter is for which seat (there is no "one size fits all" for explanations here). Most flight attendants are busy getting their supplies ready for your flight. If you still require more help finding your seat, step into an open seat near the row and once the flight attendant comes around to check on your seat belt, you can ask them then.) When you have located your seat, place your smaller bag under your chair, and look for available space in the overhead bins for your larger carry-on. This isn't always the easiest task, so turn to a flight attendant for assistance in searching or placing your bag if necessary. When you're finally able to get in your seat, place your smaller carry-on under the seat in front of you. You're all done! Now it's time for you to sit back and relax while you are carried away to your destination in luxury. During the flight, you will sometimes be offered a free drink and food (depending on the carrier and length of the flight). If needed, there are restrooms in the front and back of the plane. Any other questions can be directed towards flight attendants.
Summary:
Wait for the announcement to board. Get your boarding pass checked. Walk down the hallway that leads up to your plane. Enter the aircraft. Stow your carry-on items. Get settled in.
