I recently came across this site on tumblr called Boss Bitch Tips, and I have to say that it's such a confidence booster. They give you great tips on how to be a strong woman and I've spent nearly an hour on it lololol.
The one that really caught my eye was this one:
For as long as I can remember I've always been comparing myself to others. I felt that everyone I knew was much prettier, smarter, funnier than I am, and I went through some stages of depression and put myself down. It's hard not to compare yourself to others, I know, but from what I've learnt it's not necessarily a good thing. Sure that girl you know might look prettier, but is her smile as beautiful as yours? Does she seem happier than you do? Everyone compares themselves to others, and hell maybe the person you're comparing yourself to might even think the same of you! ^^
So guys, stop comparing yourselves to others 'cause you're all beautiful! Trust me ^3^ Just listen to Lady Gaga's song "Born this Way" and it'll definitely give you a boost of confidence ^^
