You should never be ashamed of using a personal organiser. I do not react to the people that say 'Oh are you still using one of those' as they wave their shiny new smartphone in front of me.
If like me you stopped using your personal organiser and went electronic until you realised that things electronic are not always the best solution... and then you resorted to using your organiser again. I do not regret that time I spent using the electronic version. It has been worthwhile in helping me focus my mind on what I need to record or write down each day/week.
I'm sure a lot of you might still have your first Filofax, get it out again and consider using it for a week. Naturally you might get even more comments from the smart phone brigade, but there might be a few looks of admiration too.
Owning an older style leather organiser has a certain 'retro' touch to it.... just like I can still pull out my Psion 5mx or my Nokia 7110 phone, both ancient technology from the 1990's. But that is what I used, the Psion certainly up to about 2004!
I recently had a bit of a frustrating time once again with an electronic task manager, I went back in time to how I used to do things on the Psion and then from there decided on a paper equivalent for routine weekly reminders.
So rather than trying to invent something new, sometimes it is a good idea to look back at how you previously did things and see if you can adapt old techniques and apply them to your current situation.
