Then you could never travel back, except for if you figure you can't change your own past and therefor must hide and live as a hermit, so that no-one would know you're still there.[/quote

That's not what I mean. What I mean is that if you travel to the future without anyone knowing it (maybe without anyone knowing time travel even exists), they'd think you've dissapeared. So by traveling to the future, you've changed it. When you travel back to your own time, the original time-line would be restored, and you wouldn't have 'dissapeared', because.. there you are.
My point is, you could never travel to the future and see your future self.[/color
