At the age of 19 months, Helen Keller lost her vision and hearing due to an illness, which made her learning extremely difficult. Luckily, at seven years old, she was introduced to Anne Sullivan, who became her lifelong teacher. With Sullivan's assistance, Keller learned to read and write using Braille. In 1904, she graduated from Radcliffe College with a BA in philosophy, with which she became the first blind and deaf person ever to obtain a college degree.
Unlike Helen Keller, Albert Einstein seriously struggled with his academic performance in his early life. After years of difficulty at school, however, he finally found his passion in science and mathematics. At 26 years old, he received a doctorate in physics from the University of Zurich. Then, Einstein started doing some of the most groundbreaking work in the history of the field, including his theory of relativity, which changed the field of physics forever and earned him the Nobel Prize in Physics in 1921.
Despite their incredible achievements, both Helen Keller and Albert Einstein remained lifelong learners. Keller continued reading and writing all her life and she published 12 fantastic books, including her inspirational autobiography, The Story of My Life. As for Einstein, after receiving his Nobel Prize, he continued researching new ideas and stayed active in the scientific community until he passed away in 1955.
The lives of Keller and Einstein are proof of the importance and value of lifelong learning. Through their hard work and dedication, they showed that anyone can achieve greatness if they have a strong desire to learn.

A SHORT HISTORY OF THE SELFIE
They're everywhere - people posing with their phones held out in front of them or on a selfie-stick. And it's not just young people - social media users of all ages take selfies, including space-walking astronauts and the Pope.
So when did this selfie mania begin? I. Most people would guess that it was around the beginning of this century or perhaps a bit later when smartphones became mainstream. But most people would be wrong, just as Britney Spears and Paris Hilton were wrong when they declared on Twitter in 2017 that they had invented the selfie eleven years previously. In fact, they were around 167 years too late to make that claim. II. The oldest existing selfie dates back to 1839 when photographer Robert Cornelius took a self-portrait photograph of himself. III. Cornelius couldn't take a dozen shots and choose the best one-his selfie had to be just one photo. Half a century later, in 1914, thirteen-year-old Grand Duchess Anastasia Nikolaevna of Russia took a picture of herself in a mirror and became the first teenager to take a selfie. IV.
And what about the origin of the word itself? It is thought to come from Australia where people have a habit of putting -ieon the end of words - barbie for barbecue, postie for postal worker and even Aussie for Australian. In 2002, an Australian man took a photo of an injury to his lip and put it up on a public forum to ask for advice on how to treat it. He referred to the photo as a selfie, and the term was born. Selfie became Oxford Dictionaries' word of the year in 2013.
So, why do we take so many photos of ourselves? A 2017 study into 'selfitis', as the obsessive taking of selfies has been called, found a range of motivations, from seeking to feel more part of a group to shaking off depressive thoughts and of course - capturing a memorable moment. Since we live so much of our lives online, there is pressure to present good quality images, and so it is no surprise that airbrushing apps that enable people to retouch images and present an idealised version of themselves are gaining popularity.
