You're very Welcome. I don't really agree, because opportunity cost (correct me if I'm wrong) is what you sacrifice and while you might sacrifice some other activities, that in reality are not as important as your priorities, you're actually gaining time, get more done in less time which leaves more space, time and energy after you've finished your main tasks. You can do many tasks in a day, I certainly have more than 3, but it's about having a structure and achieving a focus. Going one step at a time will get you further than trying to jump over a stai rcase.
