How it's used

This idiom is used to critique someone who spreads their focus too thin across many skills without achieving mastery in any. It carries a slightly cynical or cautionary tone, often directed at people who are indecisive about their career path or hobbies. It highlights the frustration of having broad but shallow knowledge.

Examples

He changes jobs all the time; he is really a jack of all trades, master of none.
Why are you learning so many things? Be careful of being a jack of all trades, master of none.

Common phrases

having many skills

Common mistake

Learners often mistake this for a compliment about being versatile, but it is almost exclusively used as a criticism or a warning. It is not a neutral description of someone with many talents.
