Accelerate to speed close to c moving with comfortable acceleration 9.8 m/s2 - it only takes a year or two to approach c. After that move over circular trajectory (with the same 9.8 m/s2 till your velocity vector aligns with the direction back to Earth. Start decelerating with the same 9.8 m/s2 acceleration - and you'll arrive on Earth with zero velocity and a few years yonger than your friends without need of yet-to-be built warp drive (which require such exotic thing as negative energy to work). But you are NOT moving into YOUR future any faster than non-moving observers: you still age with the SAME rate as you did before travel.

So, atomic clocks in Colorado run faster than atomic clocks in Washington DC due to higher elevation (less gravity), but their proper time rate does not change regardles their motion or change of environment (gravity).

So, such "travel into the future" is no different than freezing yourself for a few decades or so in the freezer, and then warming up later to "arrive" to the future.
