In any activity (e.g. book clubs and art groups, Women's Institute and Lions and Rotary Clubs, committees of all sorts, amateur orchestras, choirs, music and drama groups, and even Internet forums), the typical membership will fall into two groups.
There are the 20% who are givers - the organizers and the do-ers (e.g. chair, committee, coffee makers, note takers, those who answer queries on Internet forums, etc.). They are what keep groups alive.
The remaining 80% are the takers - they attend meetings and take part in events, and lurk on Internet forums. It is always a challenge to turn takers into givers.
I was always making notes on scraps of paper about tips and facts I'd read in books and magazines, seen on the Internet or on TV. So this is my paperless filing system for all those bits of information I want to access easily. (Please note: I live in the UK, so any financial or legal information relates only to the UK.)
