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.

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.

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