Quite a couple of them actually. Like that you have to love yourself before you love someone else fully. That true friends are a gift to be cherished, and they hide in people you never thought would be there. That you shouldn't meddle in other people's problems, no matter how good your intentions are, it tends to backfire on you. That blood is thicker than water, and no matter what you think your family does love you more than anyone else, they just have odd ways of showing it sometimes. That love is something special, and so is sex, we don't cherish it enough and we don't look after it and nurture it.
There's a lot of life lessons I learned the hard way, please share some of your wisdom with me too?
