In my opinion, no you're not. A lot of magicians think learning flourishes is just a waste of time, and that you should let the trick speak for itself. And that's how I feel. Usually people who start learning flourishes aren't interested in magic, and just want to be able to do some XCM (Extreme Card Manipulation).
I bought a video on flourishes to add to my magic. I can do a majority of them, but found I very rarely use them unless someone comes up to me and asks to see something crazy. They'll be impressed, no doubt. But the trick that I perform right afterward does a lot better.
However, some tricks have flourishes added right to them. Vapour, for example, comes with a nice flourish. I think that flourish is sweet, simple, and very appropriate. I honestly, would not like to that see Vapour performed any other way.
Of course, this is all my opinion. But I think it's safe to say, at least a couple magicians will agree with me that learning complicated flourishes, flips, and "doo-dads" is really not worth it.
