Keep agreements that you make, and make agreements that you can keep.

from the book It’s Hard to Make a Difference When You Can’t Find Your Keys

I didn’t read this book, but a friend shared this quote because I’ve been quite frustrated by people canceling and changing plans and promises made in various contexts with sincere intent but without being realistic. To me, this is equally as irritating as being late and has similar consequences, especially when it happens frequently. If you’re a repeat offender, check in with yourself and your ability to follow through before you commit.
