Hold.

Kent, unknown

Hold on to what is good, even if it is a handful of earth. 
Hold on to what you believe, even if it is a tree which stands by itself. 
Hold on to what you must do, even if it is a long way from here. 
Hold on to life, even when it is easier letting go. 
Hold on to my hand, even when I have gone away from you.

- Pueblo proverb
