How to Be Confident?

Surround Yourself With Positive People
Take a moment and think about how your friends make you feel. Do they lift you up, or do they bring you down? Are they constantly judging you, or do they accept you for who you are? 
The people you spend time with can influence your thoughts and attitudes about yourself, perhaps more than you realize. So, pay attention to how others make you feel. If you feel bad about yourself after hanging out with a particular person, it may be time to say goodbye. 
Instead, surround yourself with people who love you and want the best for you. Seek out others who are positive and can help build your confidence. Self-confidence and a positive attitude go hand-in-hand.5
How to Create Truly Supportive Friendships
Take Care of Your Body
This tip for how to be more confident is based on the idea that it’s hard to feel good about yourself if you’re abusing your body. When you practice self-care, you know you're doing something positive for your mind, body, and spirit—and you'll naturally feel more confident as a result.
Here are a few self-care practices linked to higher levels of self-confidence:6
Diet: Healthy eating comes with many benefits, including higher levels of confidence and self-esteem. When you fuel your body with nutrient-dense foods, you feel healthier, stronger, and more energized, which can result in feeling better about yourself.
Exercise: Studies consistently show that physical exercise boosts self-confidence. For instance, a 2016 study found that regular physical activity improved participants’ body image. And when their body image improved, they felt more confident.7
Meditation: More than just a relaxation practice, meditation can help boost self-confidence in several ways. For one, it helps you to recognize and accept yourself. Meditation also teaches you to stop negative self-talk and disconnect from unhelpful mental chatter interfering with your confidence.
Sleep: Skimping on sleep can take a toll on your emotions. Conversely, good-quality sleep has been linked with positive personality traits, including optimism and self-esteem.8
Caring for yourself is important to self-confidence. Make sure you are getting what you need to feel good about yourself and your abilities.
