wow, stay natural & be your self. theres nothing more anybody can ask from you, you should worry about other things in the world like starving children instead looking "pretty", what is pretty now-a-days anyway???
Make a habit out of it :) Do it until it's like a routine To be pretty just take care of yourself, don't wear too much make-up(trust me on this one) & to be pretty you gotta have a nice personality too and smile!!! - hope this helped!
