Barriers to Achieving Excellence

Well there are more than a few barriers, & this being the IT world, there are more than a few sources.  But I think that the damned weather must be up there with the top few.   Cold, wet, seeping, weeping rain puts a damper (!!) on any job, especially if it's outside, or underground, i.e. a data cable in a conduit, connecting to a Wi-Fi access point.  And even worse if it's governed by the Bank of No-Cash which has provided free gash kit to do a pros job. 
My only saviour is that I am not the vendor / hired hand, just the monkey offering advice, which will probably fall on deaf ears.   Reboot kit, check cable, and curse the demons who lurk outside striking distance, but do it quietly in case they hear you.
