Focus on spheres of influence. What do you control? What can you influence? What can you be aware of. The first two should be the focus. Leave to God what is beyond your control.

This is very good advice. Part of the problem of modern tech is it makes everyone feel like they have a say in every issue...the truth is 99% of the time you are just causing yourself needless worry and agitation for something that you have no reasonable control over at all.

As an aside, I don't know if you read City of God from St Augustine, but your points mirror his. Basically:

• There is the Earthly City vs Heavenly City.
• The Earthly City is driven by temporal power and sin. Even though the Earthly City strives for peace and order it ultimately fails because humans are too sinful.
• Being saved will grant you entrance to the Heavenly City where true justice and peace will prevail, thus limit your interaction with the former and focus on the later.

"two cities have been formed by two loves: the earthly by the love of self, even to the contempt of God; the heavenly by the love of God, even to the contempt of self."
--- St Augustine
