Given a choice, people would reclaim their own baggage in life over others.

~ R’ Simcha Bunim of Peshischa zt”l

In other words, if everyone’s “baggage” or troubles were spread out on a table and people were given the option of exchanging their baggage with someone else’s, they would inevitably take back their own.  That is because Hashem gives each person exactly what they need to overcome their own individual challenges.
