Some of us have always had it in our nature to want to help others but when we were using we were always too consumed by ourselves that helping others was simply a passing thought. It wasn't until we got sober that it became more real that we could actually help other people.
In the beginning of recovery it could be something as simple as opening the door for someone. Just paying attention to those things is a drastic change from when we were using. We know we were selfish and self-centered. That is why it is such a great gift that we can help other people. Even helping outside of A.A./N.A. is such a wonderful thing. For example, volunteering at a soup kitchen, a local church or temple, etc. Anything that is giving of yourself freely can impact a life. Try it! It can be one of the most rewarding things!
