"Go to bed smarter than when you woke up." Charlie Munger
Just reading a book for the sack of reading and finishing it is not much value except you can boast of having aread a book.
Until what you read becomes part of your wisdom, not just knowledge, that reading is of not much use. You will not be in position to use that knowledge, that information you got from reading the book.
So in order to make the reading useful, you have got to have a strategy to read a book.
There is no doubt that reading makes you smarter, every page you read leaves you smarter, even if you dont remember anything from that reading. But that reading has definitely left some impression on your mind and probably on the subconscious mind.
Warren Buffett claims to read 80% of his daily time, he reads around 500 pages each single day.
No doubt he is a billionaire today.
When you read a lot, read variety, it builds upon itself over period, you generate your own knowledge and wisdom.
But a wrong reading habit can leave you exhausted, devoid of much knowledge and frustrated at the end. Because
even though you are reading a lot but you are not gaining in wisdom proportionately.
This is because your reading technique is not correct.
The way a wrong batting/bowling technique can ruin the career of an International cricketer, similarly incorrect
reading technique can damage you.
