Past or Future?

If you had an option to chose changing the past or seeing the future, which one would you choose? If this question was asked to me, I wouldn’t prefer neither of them. Lets’s think about it for a minute. If you see the future, what would be different? Let me answer this question according to myself. In my opinion any of us should know the future because our lives wouldn’t have a meaning at all. For example, many of us are waiting the new year with hope and excitement. What if we know how will we be feeling that day, who are we sitting with, what are we doing before new year, does celebration of new year has a meaning to you? To me, it doesn’t. And now, let’s think about changing the past. If we had an ability to fix everything we regret, everything we had made wrong, do you think that we could learn lessons from them? I think no. For example, you have an exam but you don’t study for it. Your exam result is not good. You are feeling very sad. Than, you remember that you can change it and go just write the correct answer to your paper. So, how will you take a lesson? Will you study for your next exam or change your answers after the exam? That’s why I don’t chose any of them. So, what is you answer to this question: Past or future?
