I do....and my day isn't half as full as yours. I think if you feel like hiding under your binkit for a few....I suspect it might make the most sense to do it.
The reason we get overwhelmed, is because the whole list of 'things to do', is present in your head at the same time.....PLUS each step (of several) to complete each task. That's a lot of what I call 'mind snot'. I know....nasty.....but really, that's what it is. The part we forget to process, is that we are not required to complete the whole list of 'things to do' all at the same time. So....clear your mind, as if you only had one thing to do. When you're done...and only when you're done...think about the next task.
