The Greatest Thing
As a precious, priceless spark of life (whatever "life" is), the greatest thing you'll ever do is recognize that same precious, priceless spark of life in other beings and know that loving and comforting them is what one should do to other beings. It makes them feel happy, loved, safe, and accepted. It makes their fears go away. Let other beings love you that same way, too. And you love yourself that way as well. Unconditional, infinite love.
Or as Nat King Cole sings...
There was a boy
A very strange, enchanted boy
They say he wandered very far
Very far, over land and sea
A little shy and sad of eye
But very wise was he
And then one day
One magic day he passed my way
While we spoke of many things
Fools and Kings
This he said to me:
"The greatest thing you'll ever learn is just to love and be loved in return"

Love you so much!

P.S. In addition to loving and being loved, life is just about having fun (whatever that means to *you*). You love yourself by seeking out and having fun.
