That is wonderful
My DS only wants to write things that are meaningful to him too.
He has a little project where he grows and sells seedlings. He writes the labels for the little pots himself and he is really very motivated there.
The other thing that happened the other night was when he pulled out my partner's Scattergories game. We played an untimed version and he stayed focused on writing down all of his answers.
He also has enjoyed writing the occasional note to remind me to do something for him.
On his birthday I gave him The Second Big Big Book of Tashi and wrote a little note wishing him happy birthday on the inside cover. He wrote "thank you for the book" completely independently and came and showed me.
