To become smart, one thing is sure that you need to read a lot. You must have come across people smarter than you (& you feel Jealous at times!) but how are they more smart? Perhaps they read more than you do and so know more than you know! All of us have 24 hours, right? So, how can you improve? It’s simple. Read more in the same time. Do you know reading speed varies hugely among people ranging from 110 words per minute to 1000+ words per minute. Only 1% people fall in 1000+ words (Smart!) category because others just don’t look after their reading speed. You can improve your reading speed by taking free reading speed tests (available online), among other measures. Then you will be able to read more & become more knowledgeable (& smarter, of course!).
