Future Twilight's life is very different compared to the normal Twilight Sparkle. At least now it's different. Before, Twilight and everypony else's lives were heading in the direction of what Future Twilight's life is now. But when Future Twilight doesn't want anypony else to get hurt, she goes back in time to stop the course of history and re-direct it.
