Enjoy life to its fullest!
We are all born for a purpose and while we may waste time on irrelevant things, our purpose doesn’t just vanish. It waits behind the scenes, and every once in a while we get clues to them. Once you step into your purpose, you immediately activate something divine about your life because the origin of all human purpose is God.
Everybody wants what they want and nobody sacrifices for the other. Therefore, placing trust in people and expecting them to be absolutely moral and selfless in their decisions with regards to others, is a difficult and untenable road. This is more so in the case of democracy where representation is prevalent. In the case of communism, I imagine everybody would have to genuinely care about everyone else which is almost impractical given human nature.
