Things. Stuff. Collections of ... whatever, really. Don't get too attached to things and widgets and thingamabobs and artefacts and all the other man-made objects which supposedly are there to serve you but which end up needing service in some way or another, from simple storage service - where are you going to put it all - to actual upkeep. Just keep the minimal required to live your life in a way you find worthwhile and decide that anything more is optional. That doesn't mean you need to go out and actively get rid of stuff to lead some ascetic life of frugality, it just means you might want to dump it the next time you move without bothering to bring or replace it. Make sure whatever you have and keep around you is there to serve you and don't fall for all those gadgets which are being pushed upon you.
