Prevent the Holocaust of WWII.
If you could change the past, what's one thing you would have done differently?
I wouldn't change a single thing, this is my path already, i am who i am today because of the decisions i've made yesterday, the mistakes that i've made gained my experience, i can learn lessons from them & do better the next time. That's the point of life, to know there's no rewind, so make sure you use the opportunities you've got in the best way & do what you feel is right, then when it turned out wrong, learn from it & make a better move the next time, sometimes the mistakes makes us fail, & the failure makes us to realize our flaws & wrong movements, then it makes us to realize the meaning & the value of success & how it can be cheerful to win by a hard work & trying over & over.
I wouldn't believe what my grandson posted of FACEBOOK that was a stupid tag hoax about me going to be a Great Grand Ma next year! I hate Facebook!!!! MY DUH! :(
Stayed In college and got a higher degree
Worried less than I have about what other people think of me. I don't really care that much now, but I used to be really worried about that sort of thing.
