if you are going to be good, be good. if you are going to be bad, be good and bad.

You can definitely change your future. Use the knowledge of your past to decide what path you want to go forward on. You are responsible for your actions and the consequences thereof. Live the good life, you only have the one.

Hi Marcelo , Past ?? How could you possibly change the past unless you have one of those Back to past machines where you land somewhere in 18-- for example and take an action that will change the past as you knew it in 2008 ,which would for sure have the consequence of changing future actions positively or negatively depending on what you did there back in time . Yeh i like science fiction movies ;)

Well, actually I think you can't change your past – because, you see, it's PAST, it's gone away. All you can do is trying to know and understand it in order not to repeat past mistakes or just to improve things you can. The more conscious of your past you are, the better you'll be able to make your future.

I think it depends. If the part u changed is a bd part, surely it's gonna help u to have a better fufure. if it is on the contrary, well, maybe it will destroy your future.
