Under the umbrella that this life has some specific value (as opposed to is just an experience):
Speaking from someone who has lots of awareness of other lives, it is very hard to stay with living this life if you are aware of others. In the moment it is much easier to do what 'worked before' than to do something 'more appropriate' for the current situation.

Back when the New Age movement was strong, I saw so many people learn about their past lives only to blame their current problems on those past experiences. This blocked them from solving their current problems. Yes, some times the root of their current issues are from past lives, but that does not change the fact that they need to resolved them now.
