Mood and business development I have a couple years hearing from different "gurus" the link between mood and successful people, these gurus argue that there is an important relationship between the level of optimism and the success rate which business people have. If you want to be a successful man or woman, then you should be an optimistic one. The problem with this sentence is that it sounds simpler than it is in reality, because frequently, people could confuse optimism with naivety, and therefore frustrations disappointments start to invade of entrepreneurs state of mind. The point is, yes, you should be optimistic, because recent studies about psychology demonstrate that an optimistic individual is more likely to identify opportunities and discover new perspectives to solve problems than a pessimistic one. So, how to be optimistic without falling into naivety?, that is the point, you should understand and convince yourself that there is nothing impossible in this life, but some things are probable and other ones are possibles, a goal or an idea could go from the possibility to the probability at the extent of your creativity and your disposition to see the problems from different perspectives.
