A curse or a gift?

It is hard to decide if changing the past, or seeing in to the future are gifts or curses. Both could be good and bad. Those who made many mistakes in the past would probably want to change it. People who ruined their life or someone else want to do it all over again and be smarter about their decisions. Changing the past could affect the future. It could affect it in a good or a bad way. Changing something that has happened will make anyone a different person and change their personality. Everyone learns on their mistakes and if one knows that they can change what they do they will make mistakes and never learn the consequences. Seeing in to the future would not be bad. Seeing something bad is about to happen and changing it could save someones life or your own. It would be a little dull knowing eveythingt that is about to happen but could do a lot of good as well. People also fear of things they don't know, if we could know eveything we would fear less. If someone could see in to the future they could sometimes read it wrong and make a mistake. What seems liek something good is about to happen could have a twist and be very bad. If one saw something bad and wanted to warn others not many would believe it. Slowly I'm coming to a conclusion both seeing in to the future and changing the past are curses. Eveyone would like to have those two things when they want to redo something they did or when they want to see what is about to happen or who they will marry. But having those two things everyday can be very difficult. People could thing one is going insane as well, or that they are lying.
