Okay weird hypotheticals again lol:

Rules (sorry, I know someone is gonna ask for rules, cuz its a time travel scenario mmkay?):

TLDR: Basically you have 24 hours, you can end it at anytime and go back to the future, but once you end it, its over. You can only do it once. You can save this ability for any time in the future, or use it immediately.

Full rules:

  • Basically, you are back inside the body of your past self at any point in time after you were born. Obviously you can’t bring anything back, only your consciousness goes back.
  • You have up to 24 hours, you can end the time travel session earlier if you want. If you loses consciousless in your past self’s body, or fall asleep, the time travel session immediately ends.
  • You can only do this once.
  • You don’t have to immediately use it, you can save this ability for any time in the future.
  • You must be awake to use it, you can’t use it in the middle sleep of while unconscious. Although, you can travel back to a time when you were asleep and you would immediately wake up in your past self’s body.
  • When you go back, your past self’s memories are merged with your memory, and you keep this even when you travel back to the future.
  • When the time travel session ends, you return to the moment in time when you originally left, but now you are in the new timeline with a future that could have changed from your actions in the past.
  • Your past self would immediately resume control the moment you left, if you were still awake at the time of leaving. If your time travel session ended by losing consciousness, then your past self resume control when they wake up. Your past self would remember roughly what happened but wouldn’t understand that your future self was in control (unless you leave yourself a note or record a video or something), and wouldn’t retain your future memories.
  • If you end up in a timeline where you died before the moment in time when your left your original timeline, you basically just see the last 24 hours of yourself in the new timeline before you died, in 3rd person view, then your consciousness fades and you are gone.

Basically the point is to ask yourself: What are things in your life you wished you could change. Or what period of 24 hours would you like to revisit again.
