Not matter how proficient a player, there is someone to replace him when he gets injured or retires.
Do not think that your family, institution, group and generation will cease to exist without you contributions.
Someone, even better than you will immediately take your place.
Your unique role to the world is very necessary but it is never indispensable.
You are not the hinge on which the world hangs. Swallow your pride, the world will still exist without your contributions.
Be humbled, competent people like you are available to assume your role.
