In principle I love the idea. I love travelling light. I love simplifying my daily life during vacations. But in a way that's a luxury I can indulge in for a short period of time because I actually have much more stuff at home.
So once I get bored and need to read something new or do a different activity, at home is where I keep all my possibilities, so to speak. Plus I like being able to repair stuff and make stuff or paint a wall without going out shopping, so we have a lot of DIY stuff at home. I'm not sure I really want to declutter all of that.
How about you? One thing I'm good at, I don't hang on to a lot of stuff for sentimental reasons.
