I have tended to forget this important lesson of Rav Nahman so now when ever I got out I remind myself of it--to pay attention to the little hints.  [I totally forget where that is in the LeM but I vaguely think it is around vol I in the 60's,] 

There Rav Nahman says one should always remember that there is a next world and one way to do so is to be aware that God sends small hints every day to every person to remind him or her of what they need to understand. [But I noticed that for me, it might take a lot of hints until I get the idea.]
