If time travel was possible and you could go back in time to change one thing in the past, what would you change?
Would you try to change the world by attempting to kill Hitler before World War 2 starts? Would you buy stock of a company you know is doing extremely well in the present? Would you take a leap of faith that you never did, such as asking out someone you didn’t have the courage to, or moving to a city that you always wanted to live in?
If we ignored the numerous hypothetical troubles that come with time travel, such as the grandfather paradox and chaos theory, the possibilities seem endless. This is because hindsight is 20/20 and we have a tendency to obsess over roads not taken and missed opportunities. Even though we cannot change the past, we lament how if we had the choice, we’d make so many changes to make our present and future better.
Now ask yourself this question: if you from the future could travel back in time to now, what changes do you think they’d want to try to make? The thing with time is that it marches on linearly, making every moment a past of the future. A major difference in this scenario is that unlike the first scenario, we actually have the power to change in the present and the future.
So whenever you catch yourself regretting how life would be different if you had made different choices in the past, change your frame of mind. Instead, consider what changes you could make now to make your future self have less regrets. Maybe it is treating yourself (within reasonable limits), or finally taking that trip you always dreamed of, or taking a chance on something you are unsure or anxious about, or keeping resolutions on living a healthy, better life.
Although physics (currently) dictates that time travel is impossible, our minds have the power to travel in time virtually from the future to now, letting us make choices and take actions so we can live with less regrets.
