Consider the following quote:
Successful Thinking is a Mindset possessed by some of the greatest athletes, politicians and business people in history and modern day times. Some examples of successful thinking and positive mindset that come to mind are Donald Trump, who has been bankrupt three times, and Bill Gates, founder of Microsoft.
Successful people act as though they have accomplished or are enjoying something. Soon it becomes a reality. Successful people often find themselves in situations where risk and uncertainty is hanging over them and if they were to take on a negative mindset then failure would rear its ugly head. Instead high achievers embrace risk and uncertainty in difficult situations and keep a positive outlook. Nine times out of 10 usually end up with the results that they had in mind all along.
Positive attitude is extremely important, as it encourages individuals to approach each day, and each problem, with a bright outlook. In a team environment, a positive attitude encourages a team to work together with individual styles and personalities. Positive attitude is not only about choosing to have a good outlook through good times and bad, but also about learning to love what you do. I have observed that outstanding business people are successful because they deeply love their work.
This can be found in this article on positive thinking which is reference in this article on Enterprise 2.0 which is one of my favorite topics at work these days. I love to talk about how we collaborate better together to accomplish more things easier with less friction.
