well for my day job as an accts payable administrator (or whatever BS title they give me) it goes from like a 2- 8 or so... Most of the time, its stress free, but sometimes, when dealing with vendors or having to investigate payments, fees or dealing with any of our leases... it definately gets to me.... besides I hate what I do... so that doesn't help...
as a waitress? it goes from a 2-10 some nights. With a few tables, its easy, relaxed, etc... but if i can't get in the zone.... definately a 10.. then i'm running around like an idiot.
