Which pill do you take?

I wouldn't attempt to change anything "major" as it pertains to national or worldwide history. Sadly, sometimes bad things have to happen for good things to result, example Pearl Harbor. There is the story about a nuclear devastated US inventing time travel and sending someone back in time to kill Einstein, only to get back and find that a German scientist had made the same discoveries and the US was run by Nazis. I don't think me saving up money to invest in Apple will have that sort of devastation. And I think I could easily recreate meeting the mother of my children. My children will still be my children no matter what, unless I screw up the meeting. There isn't much at all that I would change in my life before the age of 21.
