to check your cash register slip for mistakes, right? do you check your coupons too? the cashier accidentally put in my $2.00 coupon as $0.20, my $5.00 coupon as $0.50 - i would have been out of almost $7.00 if i had not checked my bill before leaving the store! rarely where you’d expect them to be yet, they’re almost everywhere… you can find great business ideas listening to other products’ customers or while reading the newspaper (others have).
the better you are at listening and seeing the opportunities, the better your business sense will become. learn to turn your antennas on.
