Butterfly effect

Was checking my balance... 8-O lol oops... (ok... gotta seriously consider quitting smoking... 8-O lol)

and

had this thought....

What if I could have foreseen how I am today years back...

2 years?

3 years?

4 years?

11 years?

14 years?

17 years ago when I could have chosen to go into medical school?

Or, even further back?

What would I have done differently and how far back would I go?

Would anything done differently make any difference?

Or, would all alternative decisions I make still let to similar path after all?

This reminds me again a movie I saw way back.... Butterfly Effect
