"The meaning of life is to find your gift. The purpose of life is to give it away." - Shakespeare, watercolor by courtney khail
So often it seems people are searching for the meaning of life and this actually seems pretty close to me. Find what makes you special (whether that is an artistic gift, an intellectual gift, or an emotional gift) and share it with as many people as possible. (I'd add a few things to that- like be accepting, loving and don't do any harm- but I feel like if what you offer in life revolves around sharing the gift you've been given, then that should actually come naturally.)
