I tried to follow the concept of minimalism a few years ago. For everyone else who is struggling with it: don't stress out because you can't live with one backpack.
Yes, you can get rid of a lot of stuff and you should do it, but don't do it too extreme. I don't want to live without my music instruments or my sports (which requires a lot of gear) - don't fall into the trap as I did and feel bad for owning it.
Start small and collect all the stuff you didn't touch for more than 1 year - don't throw it away, just put it in the cellar and after a few months realising you don't need/want it give it away.
