2. Get the fuck off the internet. No, it is NOT a repository of all human knowledge. It is a cesspit of kitty pictures and porn. Escape now before the inevitable merging of its two major aspects!
Your viewpoint parallels a Grandmother's who refuses to look at the Internet because of all the bad things she has heard & also because she is intimidated by the computer.
The 'fucking' Internet is a larger repository of human knowledge than your local library. You will find more news and current scientific knowledge here than any other medium. Top put this in prospective, think of National Geographic when you were a kid. Your parents read the articles but your zipped through it looking for boobies. The Internet is a much larger version of that National Geographic.
You can sit in the comfort of your home and with the touch of a button read about Magna Carta, Julius Caesar, the real battle of the 300, watch TED talks (informative talks by cutting edge researchers), university lectures on viruses, astronomy, mathematics, geology, along with books from literary giants..... vast sums of knowledge at your whim ...
..or you can look at porn & kittie pictures.
So if we follow your advice: '5. Ignore every bit of advice you see in online fora. Guaranteed to make you at least 63.6% smarter.'
I would start by ignoring your item 2.
