I don't like my clumsiness, though I've come to cope with it by keeping my physical environment reasonably clutter-free, and by slowing down whenever the terrain seems unfriendly. If anybody takes me anywhere then I'm rather at their mercy, but these days with mobile phones it's no longer necessary to avoid losing the other people (by not following them into chaos). I think it's mostly a matter of taking your life into your own hands and refusing to go into environments that are likely to trip you over.
I don't know if I use scripts or not - these days I try to avoid creating long procedures in advance for anything, especially if other people are involved, because they nearly always change the remit after the fact, and I'm not good at editing my plans. So I try to keep planning down to a minimum, and I try to keep in mind that whatever I anticipate is likely to turn out different. I think the mistake that taught me a lot was when I first started this job. They wanted me to do this rather complicated scientific task, but their instructions seemed very incomplete and dependent on holding a lot of "common sense" stuff in memory, so I set about writing a complete step-by-step protocol, which ran to about 15 pages. The protocol was virtually perfect, and explained where all the stuff that was needed could be found. But it was all communal stuff and people kept moving it around, so the notes quickly went out of date, and I didn't want to edit it, I just wanted people to leave the stuff alone. I realised that the more detailed the protocol, the harder it was to change it, and that such protocols were almost useless for a dynamic situation.
