Our dream is the song of our soul. Life without one is reduced to a hollow existence. But life with a dream is filled with meaning and purpose.Most of us have a dream, or heart's desire. But the trouble is most of us have the on/off switch of our dream set to OFF. Whenever we say, I can’t, we set the switch to OFF. Whenever we believe we can, we set the switch to ON. Simple, isn't it? Just because I believe I can do something doesn't mean there won’t be any problems. But once I believe I can do it, I will seek solutions for every problem I stumble on. And since it is a law of life that we find what we look for, if I look for solutions, I will find them.Any worthy dream is a dream worthy of accomplishing. Once I realize I can do it, the next step is to make a commitment. As soon as we make a commitment, great power is released. What seemingly were insurmountable hurdles are now reduced to obstacles of laughable insignificance. But we won’t reach this stage until we decide to stop talking and start acting. Unless we commit ourselves, self-doubt will ferment and block our way.Our dreams don’t have to be grand to be great. An aunt of mine sold gloves in a department store for most of her life.

We experience a burst of pleasure when we share our thoughts,and this drives us to communlcate.It is a useful feature of our brain,because it ensures that knowledge,experience and ideas do not get buried with the person who first had them,and that as a society we benefit from the products of many minds.Of course,in order for that to happen,merely sharing is not enough.We need to cause a reaction.Each time we share our opinions and knowledge,it is with the intention of having an impact on others.Here's the problem,though:we approach this task from inside our own heads.When attempting to create impact,we reflect on what is persuasive to us,our state of mind.our desires and our goals.But if we want to affect the behaviours and beliefs of the person in front of us,we need to understand what goes on inside their head.
