I recently re-read the book 1984. Here's what I learned from it:

1) War is an industry.

Egotistical leaders will start wars for no reason.

Knowing what's going on around you is important, but taking ownership and focusing on your own path is MORE important.

2) Knowledge is power.

Whoever controls the media controls the population.

A lot of popular TV channels are owned by political parties and corporations.

3) Your beliefs may be wrong.

Question how you came to believe what you do.

Your parents may not know as much as you give them credit for.

4) (Most) Politicians don't care about you. They work with whoever pays them most.

Depending on who you are, the same politician could enhance or destroy your life.
