The most useful pages of a book are normally the dirtiest.
People who are open, available, approachable and always ready to serve are mostly underrated.
Your value will lure others to benefit from your rich resources but that same people will look down upon you due to your constant availability.
You will not go unsoiled so far as you decide to relate and assist others.
You may be disrespected and underrated due to your free available help to others but your value is still intact.
Your value is mostly in what you do, not merely in how you appear.
