So here’s the premise:

You find a magic pill that would, if you took it, make you go to sleep and wake up at any point in your past that you choose.  You would be the younger version of yourself, but you would retain all of the knowledge and memory of your experiences.  In effect, it would give you the opportunity to go back and have a “do-over.”

Let’s say you were even allowed to magically bring back a “Little Black Book” with notes on stocks to invest in, flights to avoid, etc.

Would you do it?  How many years would you go back?  What would you try to change? Would you make an effort to “gather up” the important people in your current life again?  Would you marry the same person?  Do the same job?  Live the same place?
