I also collect pens and music (cassettes and vynil). I have something like 6 pens and i have no clue how many vynils and cassettes :p
I also have a "mp3 collection", altough nothing tangible i do buy the mp3 version of albums that are not made in vynil or cassettes (if i listen to an artist often enough, i'll buy the album even though i'll still listen to it on spotify).
I will buy a watch next time something i like come up. Right now i have the money to buy a watch within my budget, but there is nothing i REALLY want and i don't want to go over a certaij budget (around 1.5k) because i prefer to invest most of my money (while still allowing myself to buy a watch now and then).
