First of all, be glad that you have self-esteem issues, because that’s a normal part of being a human being. If you could completely turn that off and have zero self-doubt, then you’d be some weird sociopath who nobody likes (and who secretly murders blonde prostitutes and keeps locks of their hair… or something scary like that).
Secondly, if you feel flawed or imperfect, then you fit right in with the rest of, because nobody is perfect, except Robert Downey Jr. So don’t worry about it, we all fall short of RDJ’s glory in our own ways.
Thirdly, fake confidence. It’s easy, and fun. All the things that you don’t like about yourself, just pretend like the opposite of those things is true. I tell myself I’m beautiful and intelligent all the time, and I’m almost starting to believe it!
Fourthly, don’t forget about all the positive things about yourself.
Fifthly, surround yourself with people who think you’re awesome.
Uhhhhh… yeah, that’s all I got for now. Good luck!
