Leisure and curiosity might soon make great advances in useful knowledge, were they not diverted by minute emulation and laborious trifles.
A common measure of poverty is how much money you have in relation to other people - that is useful as far as it goes, but that excludes the case of, say, a hunter in the rainforest who has no money but is not poor. And there can be a number of people with money but who can consider themselves unwanted or invisible or estranged from society.

Above all, remember that God looks for solid virtues in us, such as patience, humility, obedience, abnegation of your own will - that is, the good will to serve Him and our neighbor in Him. His providence allows us other devotions only insofar as He sees that they are useful to us.
Google has placed its faith in data, while Apple worships the power of design. This dichotomy made the two companies complementary. Apple would ship the phones and computers, while Google would provide Maps, Search, YouTube, and other web tools that made the devices more useful.
