With kids, you have to accept the fact that you are not in control of their outcomes. You plant the seeds and nurture them as best you can, but at a certain point, you have to let go. No matter how much knowledge, love, money, or advice you give them, they will fly once their own wings are strong enough. Then they will chart their own courses through life. A father must accept his children for who they are, not who he would like them to be.
