Here's the list of things I've completed. Note that this list is most probably incomplete. I might add additional details later, for now it will purely be a list. I won't be including technical stuff or writing on here, since those are works of mine, and I'm keeping this solely for media. I also won't be putting things I played/watched/read to completion in my childhood, this is more a list of favourites (marked by an asterisk) and what I've recently done, in alphabetical order.
I won't include every show I've watched bits and pieces of, only stuff I've fully watched to completion. However, I'll also put things I've watched full seasons of in here, even if the main show hasn't yet finished, to better reflect things I'm watching nowadays.
As above, I won't be including every movie I've watched. The cutoff for recency on this one is "final year of high school," unless its a favourite I watched a while ago.
