Positive people are people who find a solution in every problem. Negative people on the other hand are people who find a problem in every solution. Which one are you?
To find out look at the problems you are facing right now. What is your response when looking for solutions? Look at some of the things that are working for you. Are you capitalizing and executing on these opportunities or finding problems?
I was reading a study done at Stanford University which in essence concluded that 87.5% of success comes from attitude and only 12.5% comes from ability and knowledge.
Having a good attitude as well as aptitude is the best combination.
