Honestly, it's not worth a moment of your short life. You're never going to make a dent. The impact you can have is on the people you meet, in their lives. If you know all there is to know, you will see that we live in the same world we have always lived in. Kings, queens, priests and secret societies, the poor and the rich, the ebb and flow of good times and bad times and yes, the eternal struggle of good vs. evil. The internet is a powerful tool. But just as it can be used to spread truth, it can also be used to spread lies. If you are not keen to tell the difference, there's no knowing what you will believe and how this false information might corrupt your thinking.
In truth, you can wade through an ocean of information for years and at the end, you will be fortunate if you have not permanently lost your mind. There are few who can do this and still manage to live a semi-normal life afterward.
My recommendation to the average person: don't try it.
