The entire concept is flawed, unless you are not visible and cannot interact with the environment. Your mere presence could set of an unknown sequence of events, period. Any small change could result in a large change, perhaps not to you directly, but maybe inderictely, which in effect could direct your decisions.

Of course the concept is flawed. Time travel is inherently paradoxical. "Bill and Ted's Excellent Adventure" showed that. We need not even bother going back into time to make ourselves rich, we just have to resolve to do it in the future and our present instantly changes. Hence, when Bill and Ted needed Ted's dad's keys, they just appeared. One commented "We have to make sure we remember to go back and steal them" and the other responds "They're here, so we must have."

It's all a pile of illogic and paradox.

"Time travel is inherently paradoxical."

Well, the subject of this thread could very well indicate that, while time travel may appear paradoxical, there is some possibility that quantum mechanics will allow it. But, should this actually be possible, that there is no possibility of altering your present, or "the" present, by doing so.
