Born in one try.

Living one lifetime.

Loving takes practice,

But only one is true.

All the things you do in life,

So many things you have to do 

Have to do juuuust once.

You do not 'only live once', however.

Everyday you live.

But death? Most likely you will die once.

So take your time in life.

And make sure you live 

as if it's ending soon.
