Here's my thoughts. If one goes back in time and sets themselves up to be rich in the future it would change the person one is today therefore
altering the decision to go back in time and or if one could do it they would know what they did before doing it and have to leave it all behind in
order to do it in the first place.
If one goes back in time and does something to alter choices they made or actions they committed that would also change the persons decision to go
back in time as well as their reasoning for doing it in the first place.
The only way to do anything would be to live a life completely separate from our current one under another name in this instance.
If one goes back in time to alter events that took place which altered history and change them the future would not be what it is and therefore the
one going back in time to change it may not even have been born, never made the choice to go back, or the technology may never have been created to do
so. This would leave one in a state of an alternate reality not changing the time line.
Again, in order to accomplish the time travel at all that life can not be altered and the self in the past would have to live a life without altering
the future to ensure one has the ability to be there in the first place.
It would be possible to leave something to be found after one goes back in time in the hopes that someone will find it but one would never know if it
ever was due to the fact it had not been prior to traveling back nor would they ever know the implications of such to the future world.
One could however go back and add to the history which would create a historical inconsistency/conspiracy. So for instance one could go back far
enough that history itself is not known today, say prior to the disappearance of Atlantis and live among them doing what ever the heart desires as
modern history has no records only speculation.
One could also go back and find a cave or rock that has not been discovered in the current time, either by cave in or water submersion, and carve the
words "Kilroy was here" causing all kinds of confusion when it was discovered however due to the knowledge of time travel in the modern world they
would only have to check the records to find out who went back to that time and location to figure it out unless of course time travel is kept from
the public as a classified project and then chances are you wont be going back in the first place.
Assuming that this time travel does not also include location travel I would be stuck traveling back in the history of my location. Knowing that the
central United States was Native lands prior to the White man conquest I would go back even further, probably 5 or 6000 years and simply live off the
land peacefully taking each day and challenge one at a time.
