1) What to tell to colleagues who see your organization system and laugh a little with it? They ask if I'm not 'overorganised' but I think you can't be too organized. In the past I had a lot of trouble finding papers that were somewhere on my desk, and now it is much better. That's what I tell them then.
I think colleagues will experience that I become more efficient, and then will no longer laugh with it but becoming very interested. I now already realise that I can do more tasks in the same time than my colleagues.

2)It's also difficult to give the ticket of new bought folders,... to my boss. Setting up the system of GTD costs something. But when you see the long term view you will feel like it is worth it, but others (boss who pays that bills) doesn't see that on a long term view.
I wait to give the tickets until others experience that it really helps, and some of the bills I pay myself (like the 43 folders system that was quite expensive).
Anybody else with this problem? Or are you all managers? 
