In 1990, I was geared up to go into Theoretical Physics at
  Hampshire College.* I was encouraged greatly by an overview of a
  course called "Quantum Mechanics for the Myriad" given to
  prospective students. All eggs in one basket.* Even then I knew
  better but still, excited. Turned out the professor who gave the
  talk was on leave that year and I had to make other choices.*
  Chose child psychology type classes instead and a little
  programming. No regrets, as it gave me a greater understanding
  of "how people think" generally and tied into the whole "inner
  child" idea that I grew up with as "more or less fact" thanks to
  the "I'm ok/you're ok" type books I remember reading as a
  teenager. Still, there was the inner Theoretical Physicist that
  wanted expression. I forgot that professors name all of these
  years.* Tripped over it today, memories brought forward from
  writing about my "almost path" elsewhere and it just so happens
  the title of the talk and course I wanted in 1990 *still* exists
  and is taught today by the same professor at the same college
  and the information *didn't* disappear like most of the
  information from the earlier Internet already has. I saw this,
  and I'm proud.* Herbert Bernstein.* Never became my professor.*
  I never took the advanced mathematics and logic classes needed.*
  Never learned Prolog or LISP.* Never learned the how-tos of
  neural networking. Yet the interests remained and I'd look on
  from the sidelines, occasionally seeking information on these
  topics through the years here and there, curious about a "could
  have been life". Again, no regrets: each choice I make and was
  made made me who I am today and will become, and I'm grateful
  for all of it. But there's no harm in peeking.* In this
  alternate reality, I can cheer on the professor I almost had on
  the success he *did* have in the area I nearly worked in and
  feel as if, in some way, I'm a part of it. That's the beauty of
  alternate histories and the nature of the Possible:* If you look
  on The Possible without regret, you can _be_ all of those people
  you never were, and lead all of those lives you never led,
  because you *are* all of those people and you *did* lead those
  lives. How? In your mind.* Just as we can cheer on a fictional
  character on a movie screen, we can also cheer on our fictional
  selves, those who followed different paths in alternate
  fictional realities and in the process, they too, are cheering
  YOU on in your own life, for YOU are leading an alternate
  reality for them and they also want you to succeed and are proud
  of you. Sound nuts?* It's not. To me, it's integration of your
  fictional and real selves.
