I don't know, because I also would prefer not to know before where I am heading to. My mind works about thinking always on different and various scenarios and elaborating their possible outcomes intuitivly following my perception and analysing the present through a process of past experiences.. and probably that's why I would like more to visit the past, and yes as you said, i think would help me understand things better about the present me, since I could make a comparison about I had react in the past, determined by how I had reacted amd felt at the time, and the 'present me', so I could evaluate the progress also (if there are in first place), so I could change the trajectory, or adjust it, to the purpose of creating a future where I am more comfortable and at peace with myself.
