Confident body language means you “open” yourself up. Uncross your arms and legs, pull your shoulders back – don’t assume the hunched or closed-off posture that increases your stress hormones. [2] X Research source Before entering into a situation that makes you feel nervous (a new social setting, a classroom, an interaction with people who have ridiculed you), go somewhere private and strike a power pose for at least two minutes.

Eat healthy foods. Try to eat a healthy mix of proteins, carbs, fruits, vegetables, and fats every day. You don’t have to be a health freak to be healthy – it’s okay to eat a single ice cream cone or a bag of potato chips every once in a while. Just try not to overindulge. Your occasional treats will be more meaningful if you eat them sparingly. Get plenty of exercise. If you spend lots of time watching TV, get off the sofa and get some fresh air! Ride your bike, swim, or take a walk. Physical activity will keep you healthy and in shape.

Try searching for meetup groups online, looking for groups at your local community center, collegiate cultural groups, or ask at your place of worship.

If everyone in your group is obsessed with football, try taking an interest, too. Attend a few games and learn some of the basics. If it truly bores you, then you don’t have to stick with it, but make the effort.

If you get angry easily or have reason to think you’re depressed, don’t be afraid to contact a therapist or counselor. You aren’t a “crazy” person for talking to a professional therapist. They can be simply a helpful voice as you go through a difficult time, or something much more important.

Brush and floss your teeth. Adding flossing to your dental care routine will go a long way in keeping your teeth in tiptop shape. Put on deodorant before you leave the house. Bad body odor is a quick way to make a bad impression on the people around you. If you have extreme body odor, see a doctor for prescription deodorant.
