I just watched "We Bought a Zoo"... cute movie! It was based on a true story, which I had not realized before. There were a lot of good/heart warming/funny things in the movie but the one thing that's sticking with me was this phrase; "All it takes is 20 seconds of courage". The main character refers to this and you see it at different points in the movie.
20 seconds is not long at all. Just having 20 seconds of courage might be all it takes to make some incredible changes!
