first: my journey of live: first you have no idea who you are, second: you come to terms with you body, mind and feelings and accept yourself. third: you find someone who you believe is perfect for you and begin a relationship fourth: you break up with that persona and struggles to rebuild yourself again (repeat that a few times) fifth you settle emotionally and financially and dare to have children. sixth: you work hard to make your children share your views and values till they get puberty, then you just quit.... do i have to continue?
second: don´t worry, we are so many nowadays that, provided our planet doesn´t auto destruct itself before, we´ll perdure as race for ages!!!
