But quitting my job will mean lots of unhappy moments for the family I chose to bring into the world.
maybe so for your family
but there are many families, and i know some, where the situation is quite the opposite
for example:
the constant and deep Simcha experienced by GR, his kallah and their children (he learns 15 hrs/day or so, she works when she can, usually from home)is beautiful to see. they also have frequent financial difficulties but they deal with those also with Emunah and even, to some extent, with Simcha
