Develop your critical thinking the simplest and easier way ever: just say 'no' to everything.

"Give us your data" -> No
"Vote for us!" -> No
"Give us your money!" -> No
"Read our clickbait article!" -> No
"Like and subscribe!" -> No
"Believe in us!" -> No
"Support us" -> No
"Join us" -> No
"Obey" -> No
"Work" -> No
"Consume" -> No

Takes time to get used to it, you will think you're losing big stuff. But after a few years of practice, you will start noticing the difference and you will start appreciating what is wrong with this world. I'm not saying that you should trust me, I'm just saying that you should figure it out by yourself.
