Dilemma

Dilemma: You cannot take your "present mind" back to the past! Meaning, all that you know and all that you have learned since that time will not be applicable when you go back to where you were on a specific point in time in the past. Therefore, how do you change the past if you go back and are unaware of what it is you want or need to change? You will probably need to take some token or touchstone with you to make you do what is required to make the positive/negative change. Intriguing idea!
