Writing advice?

[ratherastory]

I posted this elsewhere, so apologies to people seeing it twice.

Okay, so ratherastory has probably bitten off more than she can chew. No one is surprised. At least I'm aiming high, right?

So I have several large projects, all of which are due in the next six to eight weeks, in rough form. These range from a couple of 10k+ commitments to 15k+ commitments to three 20k+ commitments. Yeah, I know.

I've done a couple of balancing acts in the past, but never so many at once.

So here's my question. Has anyone here done this kind of thing before? How do you manage multiple large simultaneous projects? Do you have a system? Do you allocate specific amounts of time/whatever to each project every day? Work on whichever project strikes your fancy on a given day?

In short, what's your strategy? Do you have tips? Advice? Giant heaps of mockery because I have no self-control? ;)
