Consider this, in your search for meaning in your life: The sole purpose of your life is to help one person, truly help them. You will not know who and you will not know when, but you will realise it when it occurs. It may occur early in your life or later, this does not matter. Until or after it occurs you are to simply, and kindly, enjoy your time on this planet. If it comes to be that you help more than one person, consider yourself called from retirement for your exemplary prior performance.
Remember, someone will also help you. In this way, we find each other.
