In the modern age of information, reading truly is a fundamental survival skill. You don't have to be a great reader to get the point.
Some people read fast and remember everything.
Others read slowly and take a couple of times to get all the information. It doesn't matter, really, so long as when you read, you get the information you're seeking. WHY you're reading. You don't need to read everything. Not every magazine, letter, and email you receive contains information you need.
