Product and package design, probably. Reading and watching about how X thing was created is one thing, and I learnt to enjoy it a lot thanks to Discovery, but making something someone would call their daily driver and stop even noticing is a very sweet goal. Making things just like for yourself, and not like for a faceless consumer who doesn’t know better, and testing every weird idea on prototypes until pieces fall into place. And waste, fuck it, I hate how single-use plastic and slackfill are everywhere and I wish to exclude them as much as possible.
