I used to think I was good at multitasking. I believed I could easily juggle multiple things to get through everything faster (how else would I get through the ever-increasing tasks on my to-do list?).
But I’ve since learnt there’s no such thing as being good at multitasking.
It really isn’t possible no matter how efficient you think you’re being. Even though you believe you’re on top of things, something will suffer.
