Time manipulation is built into our very languages. Look at how
  we freely create fictional alternative Universes ALL of the
  time: "If only I had done such-and-such... then I wouldn't be in
  the mess I'm in today". Fictional Alternative Universe. We do it
  all of the time. Most people find it rather depressing. I just
  find people who are DOING the stuff I _would've_ been doing if I
  had followed other paths, and I cheer them on as "alternate
  me's" that work for me. They're doing my job for me, frees me
  up. === One significant alt.universe me was gong to go into
  Theoretical Physics. [this is from high school]. Set it up as
  the major I wanted. In the end, never finished college, the
  professor I wanted for theoretical physics was away for a year,
  and I ended up doing child cognitive psych/development classes
  and programming mostly instead. In any case, had I *gone* down
  that road, I'd likely be something like a Brian Greene today.
  So, he's working for me, pursing that direction. He's doing a
  fine job, although i disagree with me on several points tongue
  emoticon == I dabbled with numerology a little bit, but once you
  get into Chinese Remainder Theorem a little or start playing
  with the bases, things get all wacky. I accidentally made an
  Ulam Spiral in Excel once. Never heard of the guy but I found a
  pattern and was like, OH I FOUND SOMETHING!... only to discover
  a dude figured it out while doodling in math class in the 60s
  and became famous for it. Oh well - glad I didn't go into math.
  == Mike Jittlov. Cult classic. He made a short in 79. Spent
  years getting the funding. Made a movie about a guy making a
  movie on a shoe string budget. Cult nerd classic. FINALLY
  released in 1988, 9 years later.
  [1]https://www.youtube.com/watch?v=3ldOTw60Ozg I saw it in 1991
  at a friend's house. ==   He hides special effects every few
  seconds in the whole film. Every special effect you see (and a
  lot of them are VERY subtle) he drew on the frames with his bare
  hands.
