Time travel! What if a future version of yourself came back through time with a dire warning? Will it cause a paradox? A rift in space-time? A barely-noticeable butterfly effect? Maybe instead of a warning, it's better to come back with inter-temporal positive self-talk. Delivering the vitally important message: "You're doing great!" Ya know, it's like Looper, or Interstellar, or Back To The Future (except with the emotional depth of a 'hang in there kitty' poster).
