I just read a terrific book by Siimon (yes, there are two ii’s!) Reynolds entitled Why People Fail. He identifies 16 reasons, addresses each of them and offers concrete and practical ways
to overcome them. Some of the reasons are Unclear Purpose, Destructive Thinking, Low Productivity, Poor Presentation Skills and Lack of Persistence. Lots of what you read is common
sense but I predict that you’ll pick up some real gems to pursue as I did. It’s a good read and could enable you to become even more successful. Give it a try.
