The writer Mark Twain once famously said, “If it’s your job to eat a frog, it’s best to do it first thing in the morning. And if it's your job to eat two frogs, it's best to eat the biggest one first.” The ‘frog’ is that one thing you have on your to-do list that you have absolutely no motivation or inclination to do and that you’re putting off because it’s hard, uninspiring, no fun or just a plain pain to accomplish.
