The metric being measured can be different from one day to the next. One day might be for learning, another day for loving, another day for helping and yet another day for sharing.
But there is one common metric that must be continuously measured, and ideally reinforced: Gratitude.
Without gratitude, you won’t be able to appreciate what makes today great, and won’t be able to fathom how tomorrow could be even better.
The answer to making tomorrow even better than today? More gratitude.
