When I was growing up my schooling was not as it should be, due to my illness. I was a quiet, shy, reserved lad. My physical ability was worse than it is today. I could not get up myself, I could not bend to dress, I had a leg brace and many other difficulties.
Once I thought volunteering was my potential and making that step out of the comfort zone was scary, even worrying but what you can gain is well worth the fear!
