I heard this in the first lecture of positive psychology.
It’s coz we’re much more alike than we’re different. So the more we understand ourselves, the more we understand the alike within all of us.
for example: all of us just want to be love in the end. to be able to recieve and share love. that’s a common theme that comes up in 2 am conversations bettwen the diverse-est of strangers.
