icot-I think you got it.
I was supposed to make a very big move. There were many technical details that I was very worried about. (It was from one country to another.) I was worried about having beds to sleep on and furniture…..The day I was supposed to move ended up being the first day of shivah for me and my family. While I was sitting on a low stool for seven days the move seemed pretty unimportant. Suddenly most of my “problems” and worries seemed very trivial. When I did finally move it was with a very different attitude. I did not really mind that we had to sit on boxes instead of chairs etc.
I think the point of the author is that if you go through life with the proper perspective, we will realize that all the little tzaros are just minor things that don’t really matter and gam zeh yaavor.
Obviously, if your tire is busted you need a new one, but do you think it’s the worst tzara or do you fix it and go on?
