If you are committed to a purpose, it will happen. Nothing can stop commitment to a purpose.
Not a commitment to a person. That is not for you to control.
Not a commitment to the choices of another. That is not for you to control.
Not a commitment to exact results. That is not for you to control.
Your commitment must be to a purpose – the purpose could be love, or usefulness, or encouragement, or support, or service.
Whatever your purpose, commit to it and it will happen.
