Dear David,
I'm glad that you could write to me to talk about your worry and ask me for some advice.As your best friend,what I want to say is that I hope you can give it your best shot.Don't lose your confidence,and just do it.
Well,first of all,as you are not only familiar with London but also good at communication, being a volunteer must be a good choice for you and you can do it well.Then,being a volunteer of the 2012 London Olympic is a great opportunity for you to practice your communicative ability.Therefore, I advice you to grasp this unique chance.Last but not the least,if you desire to do something well,you should give it your best shot and keep going without giving up.Become a great volunteer of the 2012 London Olympic,I'm sure you can do it.
Great works are performed not by strength,but by perseverance.Since you've chosen to become a volunteer,you should keep it going.You can do it!
Best wishes!
Yours,
