Sharing means giving of our resources to someone else in need.

This can have real value for the recipient(s) and the giver.  It feels good to share.

It is important, however, not to deplete ourselves to such and extent that our own needs are are not being met.  This leads to burnout.  Balance is the key.  It is important to remember that no one person is the sole repository of goodness in the world.

Sometimes giving to someone who doesn't really need our help can foster excessive dependency on us, which is not helpful and may even be harmful.  It can inadvertently rob someone of an opportunity to experience their own ability to solve problems.  Giving just enough help and not too much is the optimal way to share.
