Sleeping is nice. We will forget about everything for a little while.

in the end, only three things matter most : 

how fully you lived, 

how deeply you loved 

and how well you learned to let go of things not meant for you

Kill nothing but time... 

Leave nothing but footprints... 

Take nothing but pictures... 

Keep nothing but memories...

Being single is not necessarily a bad thing. 

It is much better than being in an unhealthy relationship with the wrong person.
