having self esteem and being confident ain't the same as being conceited

I recognize I'm not the best one to talk about this, because my self-esteem is quite close to the floor (because of gravity, of course). But, girls and boys out there reading this: you are beautiful. In your own special way. Another cliche, I know, but again, it's the bare truth. Type in google "Who's the cutest?" and click "I'm having luck". Then read and BELIEVE it. Love hasn't knocked your door yet? It's okay, don't rush things. That doesn't mean you're worthless. Everything that is meant to happen will happen. They say that you have to love yourself before wanting anyone else to do.
If your sighing for someone who doesn't even know you exist, remember that there's someone out there sighing for you, and who you don't notice. Imagine, your future husband or wife is walking this planet right now. The person who's gonna steal from you your first kiss breathes somewhere in this planet and you still haven't met him/her.
Learn to look at your virtues and to love your defects, because someday they'll be the things someone loves the most from you. That doesn't mean you are cocky.
