Why am I not pretty enough?

Question of the year... that no one in man kind could even answer, that goes to you Albert Einstein.
Why am I not pretty enough? something I ask myself in the mirror everyday before going to school to see the popular perfect girls that put so little effort in there clothes and hair but still look better than me,I feel like my face is so heavy from holding all foundation and blush PLUS highlights and I still feel as if a boy will maybe fall for me while looking like my face is melting.Of course theres a girl that will put off the rest and be funny and sweet and kind, and get top at every subject and most votes in whatever and a girl that participates in everything and is down to life wins the race they say slow and steady always wins the race but I gave up on that a long,long time ago.
