(Do Not) Burn the Midnight Oil
According to experts, working late at night can be harmful for health. A good sleep is extremely essential to maintain a healthy body. Also, too much use of caffeine to stay awake is not good for the body.
Imagine a situation in which you have a deadline to meet, and prepare for an important meeting with some clients the next day. It's 11 pm, and you, along with your colleagues are racking your brains out to complete the task at hand. You all sit through the night, sacrificing your sleep and personal life.

Does this situation seem common to you? Sadly, this has become quite a common phenomenon these days. In modern-day offices, the pressure of work and deadlines compel a lot of people to work late until the wee hours of morning. So when someone says that they've been 'burning the midnight oil' to complete a task in hand, it implies that they have been working hard all night. Of course, in olden times, when there was no electricity, oil lamps were used at night, hence the phrase.

Though this is a very old phrase, since oil lamps have become almost redundant today, it is still commonly used. It simply means working hard doing something late at night. Of course, these days, oil lamps have been replaced by electric lamps and lights, but that's not the point.

Quotes:

"According to a study from the Walter Reed Army Institute of Research, sleep deprivation reduces our emotional intelligence, self-regard, assertiveness, sense of independence, empathy toward others, the quality of our interpersonal relationships, positive thinking, and impulse control. In fact, the only thing the study found that gets better with sleep deprivation is "magical thinking" and reliance on superstition. So if you're interested in fortune-telling, go ahead and burn the midnight oil."

"Long hours, hard labor, or burning the midnight oil will not produce a Milton, a Shakespeare, or a Beethoven. People accomplish great things through quiet moments, imagining that the invisible things from the foundation of time are clearly visible. You can imagine."
― Joseph Murphy, Believe In Yourself

"Sweet moonlight, shining full and clear,
Why do you light my torture here?
How often have you seen me toil,
Burning last drops of midnight oil.
On books and papers as I read,
My friend, your mournful light you shed.
If only I could flee this den
And walk the mountain-tops again,
Through moonlit meadows make my way,
In mountain caves with spirits play -
Released from learning's musty cell,
Your healing dew would make me well!"
― Johann Wolfgang von Goethe, Faust
