plus you'd be able to make billions on the stock market since you already know what's going to happen(assuming this is you in the 1970s)

[quote]The "joke" is that I wouldn't be thinking like a 15 year old, would have a different perspective than a 15 year old, would have already made the mistakes that most 15, 20, 25, 30, etc. year olds have made, and would not need to repeat those mistakes in order to learn those lessons. I wouldn't have the self-consciousness and self-doubt that most teens tend to have, I would know what is really important and what is only fleeting or temporary. I would understand what risks are worth taking, and which ones offer few rewards or gains. I would have the energy and enthusiasm of youth balanced with the experience and wisdom some people get with age.[/quote] Understood, but my point was that the mistake teenagers already tend to make is thinking they know everything about situations they walk into. It sounds to me like you'd be potentially making the same mistakes again.
