Life lesson by Magic Johnson: There is a difference between being told that something is impossible and actually finding out for yourself. Yet many people never discover what they could have achieved because they allow someone else's doubt to stop them before they even begin. A dream can be easy to abandon when the people around you question it. Over time, their doubts can become your doubts. You may start believing that you are not talented enough, experienced enough or capable enough to succeed. Magic Johnson's quote offers a different way to look at those doubts. The former basketball star believes people should pursue their dreams, stay motivated and be willing to put in the work required to reach their goals.
