Last week we packed up our lives and headed to Argentina where we'll live for the next year. Four suitcases, one duffle bag, one Thermomix and one piano (yep - a piano). OK - so it’s an electric piano and it’s less than 23 kg so we can check it on the plane ... although it definitely still counts as oversized luggage.

It’s an interesting exercise ... and a fabulous constraint.

If you had two pieces of luggage, 23 kg per person, for the next year, what would you pack?

I've been running a black belt practice for almost a decade now, and think we've done a pretty good job of rock starring income but not our lifestyle. I'm driving the same Audi A4 I was driving eight years ago. The whole time we've lived in a two-bedroom house we built on my parents’ property.

And even so, packing for the year I realised how much stuff we have that we don't really need.

I think as stuff has gotten cheaper and easier to buy (especially if income has gone up) more and more we underestimate the cost of actually owning stuff. The more stuff you have the more complicated your life is. Stuff takes up physical space, mental space and energetic space.

We'll see how I feel in a year, but right now my intent is to have less stuff rather than more a decade from now.

And to have my life be simpler rather than more complicated.
