You.

a very boring, pointless place.

Jon Healy

When someone/something makes life so much better...

A phrase yelled by a person who has just had their entire world destroyed, figuratively of course. Commonly, My World! is yelled when another person directly causes this indiscretion.

1) To have a profound and positive effect on someone.
2) Something or someone you really like.

someone who is everything to you, someone who means a lot to you and you love no matter what. someone you hope to never loose cause you would be nothing without them.
