15．If you are hungry，what do you do？Get your favourite meal and stay quiet after that？Just like your stomach，your mind is hungry，too．But it never lets you know，because it′s busy thinking about your dream lover，favorite star and many much things．So your brain just pays attention to your needs and never lets itself grow．When the mind stops growing，your creativity（創(chuàng)造力） stops．，too．
This is why we all sometimes think"What happen next"，"Why cann′t I always think"，"Why am I always given the difficult problems？"Well，this is we always use our brains to thinking of meaningless （無意義的） things．
Hunger of the mind can be actually satisfied（滿足） through reading．Because reading
has been the most educative（教育的） tool used by us which from the childhood．You have a large number of books，they will answer all your"How to"questions．When you read a book，you just don't run your eyes through the lines，but even your mind explains it to you．The interesting part of the book is always stored in your mind．The more books you read，the wider your mind will open up．Also，this improves your creativity．
Actually，I used to have trouble in speaking English well，but as I read，I have made great progress．So join me and are you waiting for？Go，get a book，and let me know!
