Schedule for those who play online for a living?

/Disclaimer/Not sure about the forum for this/disclaimer/.

Im not planning on playing online for a living, but for those who do, do you commit to a schedule? For example, do you play for most of what is considered the work day (9-5) or do you just play whenever the hell you want to that day? When you suffer a severe beat do you take a quick break, like I do, to relax or do you just push through? Im just curious as to if there is any structure to your day.
