HI Chae, Yes, the sentence "Having taken my advice, you would be successful." is a correct transformation of the original sentence into the participle form. "Having taken my advice" is a perfect participle phrase that implies the action of taking advice was completed before the result ("you would be successful"). The meaning remains the same as in the original sentence, but it is now expressed more concisely.

"Having taken my advice" is an adjectival phrase that is timeless. You can use it in any timeframe whatsoever. So this is easier than you might imagine! It is hardly possible to go wrong. The key thing to remember is that "having taken" is just a (backwards looking) adjective that you can use the same way you would use any other adjective. For example, imagine that the person is (or 'was' or 'will be') "cheerful always" (an adjective phrase). "Having taken my advice" and "cheerful always" work interchangeably in all sentences: "Having taken my advice, you were successful." "Cheerful always, you were successful." "Having taken my advice, you are successful." "Cheerful always, you are successful." "Having taken my advice, you will be successful." "Cheerful always, you will be successful." "Having taken my advice, you are being successful." "Cheerful always, you are being successful." "Having taken my advice, you succeed." "Cheerful always, you succeed." "Having taken my advice, you succeeded" "Cheerful always, you succeeded" "Having taken my advice, you are succeeding." "Cheerful always, you are succeeding." "Yesterday you were pleased because, having taken my advice, you had succeeded" "Yesterday you were pleased because, cheerful always, you had succeeded" "Having taken my advice, you might (or "would', 'should', 'can', 'could', etc.) succeed (or 'be successful')." "Cheerful always, you might (or "would', 'should', 'can', 'could', etc.) succeed (or 'be successful')."

Sentences #1 and #2 do not have the same meaning. #1 means "you did NOT take my advice, but you would be successful if you had taken my advice". #2 does NOT say that "you did not take my advice". It only says that taking my advice makes you successful. In fact, #2 can also be interpreted to have an opposite meaning from #1. #2 can be interpreted to mean "you DID take my advice, so you would be successful. They are very different sentences.

#2 should read, "Having taken my advice, you will be successful." "would be" implies something that did not occur, but would have, had the person acted differently. eg: If I had gone to law school, I would have become rich." Versus, "having gone to law school, I will become rich."
