I learned long ago in corporate upgrades that respect for hours = good work, that 2:30 am is NOT the time to perform a server upgrade or migration. A co-worker, former Marine, also said that if they (client) are badgering you about work, then work more slowly - drive's em crazy. I do my best work when I know what I am doing and can think clearly about it, and if the client wants a ton of work done fast or long, then be up-front and tell him NO, I will do it the RIGHT WAY and that's it, PERIOD, END OF DISCUSSION. As a field of work, we can wipe out of business in a heartbeat. It is important for both the client and ourselves to ensure proper train of thought and protocol.
