hi, love your question sammd,my wife taught me how to be tidy in a matter of weeks, she actually nailed anything i left lying around on the floor and i mean anything including my wallet,, sox, underwear even my watch, over the weeks she was doing this it must have cost me a fortune, (thank god i dont have false teeth )since then i even do the dusting etc, have a go it might just work for you.
sammd you should always start the way you mean to go on .I trained mine from the beginning now he can do everything that needs doing . If he died I would not get married again ,all that training and rewards stuff ,fun when I was younger but not now !!!!!
