I would definately be so curious to know how my life will turn out, whether I'll be successful or whether I'll have kids or whether I'll get to live to my eighties or whether I'll get to see my mom's wedding. However, I believe that I'd be quite unhappy in the long run, since even if I could use it for the good, I'd know it all and I wouldn't be able to change it, since that's the way things are meant to be. I don't think that if in some universe this existed, you'd be able to change the future, after all it is something that is technically written in stone, if you are able to predict it because it'd mean that things are not just random things bumping into each other but that some events just have to happen. This would probably steal the randomness of life, which is what makes life what it is.
