"Jack of All Trades, Master of None"

Now the phrase fits me. Before I was "a master" of something thanks to luck and 15 minutes of "fame". Past life. Healthier nowadays. 

Where does the phrase "jack of all trades" come from? 

A pamphlet from 1592. It was Greenes, Groats-worth of Witte, bought with a million of Repentance from some Robert Greene, a dramatist and pamphleteer that didn't like Shakespeare. 

The first page sets the act for his text with some drama.  

Written before his death and published at his dyeing request.

Looks like this critic had enough sins in his pockets. 

The line in question was a little different thanks to the Elizabethan writing trend, but same essence. 

...he is as well able to bombast out a blank verse as the best of you, and being an absolute Johannes factotum is in his own conceit the only Shake-scene in a country.

("Johannes factotum" means "John Do‐everything" and the accusation was against Shakespeare - or so it's said.)

Reading the original is pretty hard, but you can try. Good luck!
