Happiness is about being proud of who you are. Be a good friend, be a good daughter, be reliable, be willing to laugh when things get tough, compliment other girls, care about your job, believe in yourself, be vulnerable, tell the truth, apologize when needed, forgive people...
Kids take work, effort, love, blood, sweat and tears and are a full time job. You have to commit, for better or worse and then give your all and hope for the best. The one thing you can never, ever do is give up and say, 'Oooops, never mind, my bad, you can take this one back'!
