To truly be an activist, you need to understand what others are feeling and sincerely care about them and their plight. What you do not experience can be difficult to fully understand. Tourists and natives live a very different experience. I know as a doctor that I did not truly understand my patients' experience until I was a patient. When you step outside of your own experiences, you broaden your perspective and begin to take on a humanistic approach to life.
For this exercise, choose someone whose life is nearly the opposite of yours and visualize yourself in that person's place; become aware of how you feel and how the person might feel and why. What difficulties does this person face that you don't? How would you handle them if you did? When you acknowledge those with more troubles than you and reach out to help them, it provides your life with meaning. By becoming unselfish in thought and deed, you take the emphasis off your own troubles, and when you do this, you will be surprised by how much better you feel about your life.
The next time you see or meet someone who is down on their luck, think of what that must feel like and how the person might have gotten there. Be kind. If you offer nothing more than your time and thoughtfulness, you will make a difference.
