Have you ever not wanted to do something so badly? Well，that’s how I      about joining Madcaps，a mothers and daughters’club assisting charity.     ，my feeling changed finally. Now I believe if you adopt an      attitude．you might just   enjoying it.

Six months ago，my mom told me the club asked us to work as    at Saint Vincent de Paul Homeless shelter．That meant I had to      in the dirty homeless shelter for at least  20  hours.

The first lime we went there，a lady led us to the kitchen where we      my five fellow Madcaps classmates- they also wore the same mark .Since I′m usually      awkward， I had never talked with any of them .Worse still，my mom was asked to help outside the kitchen，leaving me totally      to serve food with them. Soon large numbers of homeless families     in like rushing river．A little girl，around 5 years old，walked up to me I   her a sandwich. She took it and joined her family quickly．As she walked away, I      she was wearing a coat．Clearly too big for her, hanging      on her thin body, and couldn’t help thinking how much I had      with her．It suddenly struck me that how      I am.

After that moment I had a    of heart Now I love Madcaps and don’t miss one meeting I have      awkwardness when communicating and have many friends. And this year I am sure I will do more than the     20 hours of charity.

So that is how I have made a    by doing one thing I do not want to do .If you have an open      about things you can accomplish more and become a well-rounded（全面的）person.
