There's a quote by Mark Twain that says:
"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."
– Mark Twain
Assuming you, like most people, have no desire to eat a frog, what does this tell us?
It's a reminder that you should take care of the most challenging task in your day as soon as possible.
If we take care of this challenge first, then our mind is clear and we can focus on other tasks. If we let that challenge sit and fester until the end of the day, then our day is spent distracted by this undesirable task.
The frog needs to be eaten. Do you rip the band-aid off, or do you let it ruin the rest of your day?
