When I was younger I used to write stories constantly. When I was around 10-11 I wrote about 30,000 words on a fantasy story that was basically about cats lol (but with warring factions and mystical creatures and stuff). Had a couple of other stories I wrote a few thousand words on. I would also always make graphs and tables and create my own "top trumps" style things with characters of my own creation. I also wrote a couple of orchestral pieces (all in C, with instruments jammed together senselessly and no proper knowledge of music theory lmao, but some of the melodic hooks were passable). I only did a small amount of poetry, never thought I was good at it, but I got a prize in I think year 6 for some poem. I joined a band when I was maybe 13 or 14 and wrote lots of songs (some aren't bad lol, sadly the band finished with uni starting) and lyrics for them (I sang and played the guitar). More recently I have been less and less creative in the traditional sense; in Year 13 when I wasn't writing any more songs I channelled most of it into English Literature A Level I guess. Now I'm at uni and the extent of my creativity is having to come up with ideas to solve maths problems, which is more creative than most would assume but I still wish I was creating more.
edit: Also I play chess but I'm pretty **** for the amount of time I've played although I do come up with pretty tactical ideas once in a blue moon
