The difference between the right word and the almost right word is the difference between lightning and a lightning bug.― Mark Twain, The Wit and Wisdom of Mark Twain

Meaning: Saving a small amount can be a poor bargain if it creates a much larger cost. Judge the total consequences of a decision rather than only the immediate saving.

Meaning: A benefit you already possess may be worth more than a larger benefit you only hope to obtain. Weigh a secure result against the chance of losing it.

Meaning: Difficulty can expose weaknesses that praise or favourable circumstances leave unnoticed. Adversity is pictured as an unflattering observer, inviting an honest assessment without making hardship necessary for growth or a complete test of someone’s character.

Meaning: Unrequested advice can be as unwelcome as altering someone’s food without asking. Check whether help is wanted before assuming you know what another person needs.
