Oh gosh I certainly didn't mean to invoke overwhelm!!

I would start with your home. (Because that's where I started and it worked out pretty well!).

You could do it room by room, or just start very simply by choosing one small thing per day to declutter - like a shelf or a set of drawers.

I had some time off work and just went through my entire house one room at a time. :)

One thing that really helped me was reading some of the Minimalism blogs that are out there on the internet... there's loads of great stuff and helpful advice on those!
