Everyone has some sort of goal in life. For some they are very lofty, very ambitious. To have that sort of idea requires lots of work, dedication, persistence and perspiration. A lofty goal can also be one that is unattainable and unrealistic but there are people who are working to make their dreams come true.
Then there are people who are of a status that puts them in their minds above everyone else. They treat people as less than and have a superiority complex.
Great speakers are gifted in their oratory and eloquence as they inspire people to ascend to new heights and to be something better. They can challenge people to rise up to a challenge and to achieve something great.
