Not A Poet
Even here at Passions you will get some similar comments. They do have a valid point of view too. The point being, in Shakespear's time they not only wrote that way, they also spoke that way. They wrote in the language of the time, you generally are bettor advised to do the same, write in the language of your time.
That said, I have to confess that I do occasionally enjoy writing in an archaic style. I don't do it often and have even been tolerated if not fully accepted doing so. There are a few points to consider though.
Learn how the language was used. Don't think you can just write thee or thou instead of you. There is much more to it than that. If you want to write like Shakespeare then study and do it right. And never mix it with modern language, words or ideas.
Some subjects are better dealt with using current language. You need to carefully pick your subject before committing to old language. When speaking of the right thing, it can be beautiful.
Finally, don't do it all the time. If that's all you write, you better be damn good or you will get boring in a hurry.
