The Real Meaning Behind “A Jack of All Trades”

We’ve all heard the saying:
“A jack of all trades is a master of none.”

Usually said as a warning — don’t spread yourself too thin.

But here’s the twist: that’s not the whole quote.

The original version from the 17th century went:
“A jack of all trades is a master of none, but oftentimes better than a master of one.”

Back in the 16th century, being “a jack of all trades” was actually a compliment.
“Jack” simply meant an everyman — someone versatile, adaptable, and capable in many areas.

There’s even folklore that it was said of William Shakespeare, who wasn’t just a writer, but also an actor and director — a creative generalist long before the term existed.

Over time, the second half of the saying was dropped, and the phrase shifted from praise to caution. But in a world that values innovation, adaptability, and cross-disciplinary thinking — maybe it’s time we reclaim the original meaning.
