I would say it is not a matter of reducing your stuff to an absolute number, but removing what is really unnecessary and/or redundant, trying to reach a minimum. Before buying anything, I ask myself "do I really need it? can I live without it?". After living in 12 different places, I was gradually leaving a lot of stuff behind, and I became kind of minimalist in the process, being aware of how much unnecessary extra baggage you carry on your shoulders. I also think that a minimalist way of life doesn't refer only to things, but also to immaterial stuff like extra fees, subscriptions, debts, mortgages, utility bills, etc. They all add weight to that baggage.
