As a youth pastor, one of the things I do is hang out with students, obviously. Building relationships is the name of the game, and the way to do that is slowing down and spending time.
SIDE NOTE: You know your kids don't need you to spend your money on them... they need you to spend your time on them. Sometimes that sounds like more of a sacrifice to us, but that sacrifice lets them know they are worth your time. END SIDE NOTE
When I spend time with students I always try to take at least one picture of us or whatever we are doing. I like to document our time. I think it shows that it is treasured. It may end up as a profile picture on some social media outlet or it may just stay in my photo album, but either way it is a way to remember the little, precious moments.
I encourage you to treasure the small "insignificant" things.
