Dear Friend,
Thank you for your sincerely letter where you shared your dream with me. It was so interesting to find out what your dream was. I believe in dreams also. Of course I have my own dreams too. Some of them are very old from my childhood, like being a cosmonaut and flying to the moon, but some of them related to my future. I think it is very important to dream about something because every dream makes you do something fir it. Dreams may come true! Every successful person will tell you to think the way your dream is already real and came true, they suggest to think about it often and visualize it in your mind. Moreover, it is suggested to have a special board with some pictures related to your dream! Let's try to make our owns? It will be great experience! We could share our achievements. I am sure: the more we wish for something the more closer we will get to it. I look forward to receiving your thoughts on this matter!
Kind regards,
Me.
