Just curious how people feel about this. One million dollars or a one-time-use time machine. You can go back as far as you want; 5 years old, 20 years old, or last week. You will know everything about your own life that you know right now. The time machine cannot be used for monetary gains or to change the world (i.e. you can't use last month's powerball numbers, you can't warn people about 9/11 or an earthquake or a brain tumor or a heart attack) The time machine is only to potentially change your own life from a specific time and place in your lifetime based on choices you made that you want to be different (school, work, relationships, car purchases, etc) Or no time machine and have $1m cash in your room right now.
