Give a book review at the library. Desire is all you need to do any of these things. There will be obstacles, of course, but that is one thing you are used to overcoming. Mostly, you will be surprised to find how quickly and warmly you are welcomed into a volunteer organization. The rules are difference here.
People work because they want to, and because they believe and are dedicated to a cause.
If you believe too, and commit your time and efforst, you will be welcomed like anyone else. In addition to satisfaction, there are many other benefits to volunteering. In some states, volunteer work can be listed on a jkob application as valid experience without the obligation to state the job was unpaid. Some state rehabilitation agencies require that you demonstrate your rehab potential before they commit funds to your education or rehabilitation. Six months of regular volunteer work can be used to demonstrate your potential.
