If you're like me, what'll happen is that you'll find that you have no limits as far as workload goes until after the fact. There were many times later that I'd think "How on earth did I ever manage to work that hard?". Well, basically by working 14-hour days and 7-day workweeks for a couple of years.
Actually, now that Tina's taken on so much of my previous workload, I'm asking that question of myself regarding more recent workloading.
And I'm sure once I get relief from some of my current workloads, I'll be asking myself how I ever managed to do as much as I'm currently doing.
