Of course it is not advisable to make a sheet of paper that says passwords and leave it on your home office wall, though I have literally seen this in the past.
Throw out fewer envelopes / trash each week
Some institutions even reward you for going paperless
Emails will never get lost or stolen in the mail like envelopes
Reduce your financial institutions burden, thus helping you in the long run with reduced fees.
Eliminate the need to buy another ugly filing cabinet
Finally, save time, let’s do the math –
Estimate 2 minutes per envelope of opening, examining, trashing and filing
12 statements/yr x 10 different accounts x 2 min/statement = 240 min/ yr
Take back those 4 hours and do something more fun than sorting mail for the rest of 2010 and beyond
