Mostly I don’t - and when I do I probably end up doing something else anyway. Looking at my 2024 goals and follow-up, they’re mostly very broad/vague, and some (SAO, VNs) I more or less abandoned (SAO become a “whenever” thing). And I mostly set those goals cuz I saw the post.
I guess I make short term impulse goals, like
“I wanna read/reread all of xyz series”, or distant future goals like “I wanna read Fate/Stay Night or 薬屋のひとりごと without major struggle”, but with no specific timeframe.
One major exception for me was deciding I want to keep up with Yurihime magazine every month. Which meant I needed to read about 7-10 series from scratch (I’m almost there). Even there it’s a “when I feel like it” sorta thing
