Here are some tips:
- Sometimes you just have to fake it. Yeah, you read that right. The first step to being confident is to act confident. That way you will get used to that "fake" confidence to the point you won't have to fake it anymore
- Don't compare yourself to other people, especially people you see on the internet. They only show what they want you to see. No one's lives are perfect. Keep that in mind
- Don't focus on the negative. Focus on the aspects you love about yourself and embrace them. If there are some aspects you don't like, you can change them and it's ok
- Surround yourself with positive people. They will make you a lot happier and improve your confidence with unexpected compliments
- Don't worry about what other people may think. Your time on this earth is way too limited for you to care about other peoples opinions. Instead, live every circumstance without caring about criticism and misjudgments. Get out of your comfort zone and don't be afraid to be the amazing person you certainly are.
