This story has always resonated with me, but I saw it in action not too long ago. So, I wanted to share my insight.
It is an old Cherokee tale, and it is as follows:

We don’t realize how people around us can influence us. Again, small adaptations and changes over time are hardly noticeable. BUT when you surround yourself with good people who have good intentions, whether you know it or not, it starts to have an impact on your life. Somone very close to me who has always been a good person but wasn’t necessarily surrounded by the same caliber of individuals, married a very selfless man. They have been together for years now. Recently, I got to see the impact it had on her life. It truly amazed me how her thought processes, views, and behavior had changed. I instantly thought of the story of the wolf. She fed her good wolf, and it was a beautiful experience to endure! Be aware of your surroundings and if you have the choice, choose to surround yourself with altruistic people.
