Hey there, welcome aboard!
Do understand how it is to have interests in writing, fantasy books, boardgames, being in the forest; and what it is like having a mix of rotating and permanent interests.
I have learned it is wise to let my rotating interests to go at their own pace and cycle; trying to force a change causes problems. And especially when building models is involved as the ones fitting the topic go well whereas ones outside the current topic seem to have nothing but problems.
