Instead of checking Instagram, why not flip through some of your favorite memories instead?
I was reading an article a few months back that suggested keeping personal photos on your phone. This way, when you're standing in line, waiting for someone, passing time on your break, instead of looking through at everyone else's lives, you can spend a few minutes reflecting on the special moments in your own.
I think it's a wonderfully simple way to practice gratitude in life. You might even end up sending a photo or two to a friend so you can share the fond memories together.
Such a sweet idea, don't you think?
