<important issue> is an important issue that affects all of us at this time, and it often seems that solutions to the problem are impossible to find. However, I have had the chance to give the matter some serious thought and I have an idea that I wanted to present to you.
I believe that it is the duty of every American to try to solve problems, not depend on government to do it for us. I hope this idea will reach you in some way and that it will be of some service. Thank you and good luck.
