Yes I would like to go back to when I was child cause I wasn't happy in my home life. Now my dad has his own life and my mom deceased 11 years now..I often go back in years and wonder about lot of things.
The past is not something I would ever change....good...bad....it's all made me who I am today, it's brought me to this point in my life, and the best has yet to come. So for me....nothing.
I would change it by not being poor and being rich to help the people that are poor
I would love to go back to the past and know what I know now. I had to go to work early In life. My dad owned the company and he decided I wasn't going to sit home. So all my life I have made money. When I was in my teen's and 20's I bought all kinds of toys.
If I could go back and still know what I know today. I would buy the right stocks at the right time. I would also know what properties could be bought cheap and sold for millions later. I would be able to retire early and have all the play toys I ever wanted, but due to bad advice as a kid I squandered my money. :(
