I work Mon-Fri 11am-10pm and take weekends off UNLESS I have nothing planned and I am always busy. I'd never consider working at nite or through the nite as all the crazies and drunks come out to play, not always mind you as I am sure there are plenty decent clients around late at nite but I am busy enough day time to not bother.
Also despite my job, I try to live as much of a normal life as I possibly can. I like to get to bed around 11pm/midnight and get up early and work through the day like normal people.
I try to get my target number of clients (2 or 3 when I am at home) as early as poss in the day so that I can take the rest of the evening off. 9 times out of 10 I am done by 6pm and only ever actually work until 10pm if I have been pre booked by someone wanting that specific time.
If I am on tour then I try to see 4 and maybe even 5 clients in a day and usually start a bit earlier and work till a little later, maybe 10am till 11pm
