I hope this doesn't sound like a cop out. . . .

Bringing a current form of technology to help someone or a family in the past leaves one with a terribly difficult decision to make. Whom to help? How? What affects might this bring about. It would also be a big responsibility. Too big for any one person. I don't think that that responsibility is a fair weight to put on someone's shoulders. Plus, I don't think it'd be fair to help someone with my advanced knowledge of technology or the future without helping anyone else. Why should this particular person or family receive advanced help as opposed to the one down the street.
Also,what results would take place? One could assume that there would be no lasting repurcussions, but I don't work with assumptions. How could I know if the help I'd brought didn't end up hurting them. How would I know if they wouldn't use my assistence to hurt someone else? Besides, how much help could I bring? I could help someone ease their workload or live a little longer, but in the long run, how much good does that actually do?
If I were sent into the past--regardless of the time--the only thing I'd like to bring with me is hope. Hope that the future is something worth living for. Hope that although things aren't bright now, things will get better. Hope that I could be their example of making the world a better place. Hope that this sense of hope is passed on...Or maybe a laser pointer.
