Broken Promises

I will admit; one of my New Years resolutions has been left to collect dust. I had hoped to be strumming at least "Mary had a little lamb" by now. Yet, unfortunately my guitar's biggest gig thus far has been modeling for this photo.

How come we can be so quick to forgive ourselves for our own broken promises but find it difficult to do the same for others? The next time I hold a grievance against another, I hope to hear my guitar playing in the background as a lyrical reminder to play a tune worth playing.
