Dear ( Insert Name Of Friend ),
How are you doing? Have you made progress on reaching fulfilling your goals, ambitions and dreams? Have you been living your life happily? No matter what, I hope that you are happy and that you are doing what you want.
Well, me on the other hand, I'm doing pretty fine. Just the normal events that I've been experiencing on a daily basis. I want to improve my grades and make my parents proud, but it is difficult as always. By the end of the year, I want to receive straight As but I always end up messing up in at least one subject and getting a B, which is quite upsetting. But you know what? It's the effort that counts and I know that I have been trying my best and will continue persevering until I reach my goal.
Anyways, I really miss you and look forward to seeing your response. Just know that you are an amazing person and that I will always be your friend no matter what, through thick and thin. So don't hesitate to ask me if you need any help or advice.
Yours Sincerely,
( Insert Your Name )
