First off I know there’s going to be at least ONE person who comments with something like air or water, OR who will read too deep into the question...that aside (lol) What is the one thing you feel lost without? Mine would be my phone for several reasons.
Music/nature/a vocabulary. Can't seperate them, sorry.
Friendship, love, family, babies, yes, babies... That's my answer...
My creativity.
By that I mean perhaps my passion for the way I learn and or create.
That covers a vast amount of topics, but the one that really comes to mind is music.
Writing music in a way is like discovering something new, and I love when that happens.
