>>5266694The most important focus when writing a letter is to make it as short as possible while still communicating what you need it to. It's easy to write 20 pages of rambling content, but just going on and on shows a lack of respect for the recipient's time. I was always taught to go no longer than a page, but two pages isn't unreasonable. Conciseness and focus makes for impactful writing.
Beyond that, focus on highlighting what it is that you love about Ame, and how it makes you personally feel. Avoid general statements which you can't know. Ground your writing in your own feelings. A good way to start with this is to give a reason for why you've written the letter. Even if it's a small reason, something has made you want to put into words the impact Ame's streams have had on you. For example, maybe it was after a particularly long and miserable day at work that you found what you most wanted to was sit down and relax with Ame. Providing some personal context can help her understand what makes her stream so compelling for persons like you.
Finally, if you're going to say thank you for anything, leave it until the last paragraph. There are few things nicer than receiving a letter which finishes on a heartfelt thank you and subsequent sign-off. Leaving thanks until the end will also allow you to end the letter in a way which doesn't feel arbitrary. Being unable to find a conclusion to letters is part of the reason many letters simply continue ad nauseam.
Happy drafting mate and if you want to share parts of the writing, I'm sure everyone here would love to see how you express your feelings about Ame.
