I'm amazed there are not filters that simply direct EVERYONE that puts forth an interest in this field to the stickies we have on this topic.

Then go to Bob Cassidy's web site and read up on the 39 Steps to Mentalism along with EVERYTHING Bob's ever written, his philosophy being (in my mind at least) critical when it comes to understanding what Mentalism is and isn't (and most of what we see out there today under said heading is a far cry from what Mentalism really "was" and was intended to be... you can't can't get magicians to understand that though...)
Tomo was correct in telling you to outline the kind of mentalism that appeals to you but ask yourself why as well. Look at the broader side of this approach and ask yourself if you have what it takes to be the character or "entity" you envision and if it is "you". Any Character we take on regardless the role, must be something we can saturate ourselves in. I now of major actors that step into a role so heavily that they really are that person for the entire run of making the film or doing the play, etc. Christopher Loyd is such a person, I lived three houses down from him some years ago and when he was doing The Adams Family movies you saw Uncle Fester getting in and out of the car not Chris.
The point is, are you wanting to "get into" mentalism because it's the big fashion statement of magic these days (a trend that is thankfully, waining) or is it because you know you are better cut out for that arena? It's nowhere near the same thing and if you are going to look at it all as being nothing but "tricks" you will loose! (not my words, but those of many others who've been around far longer than I).
Weigh it all out and don't halfassit, no matter your decision.
