Whether you run a high school or a college, there will definitely be several occasions when you wish you could just flip a magic button and change the orientation of your students about certain issues, or just push them to work harder or something along those lines. An inspirational speaker could be the answer to your needs. While they do not perform magic, their ability to deliver powerful speeches often has incredible effects on the minds of the audience.
The particular motivational speaker to invite to your school is a question that should be determined by what you want your students to be inspired by them. If you want your students to learn the virtues of hard work, for instance, then you should get someone whose story tells of how he rose in life by working hard. If you are having issues with discipline in the school, and have been finding it difficult to handle it on your own, having a motivational speaker with a troubled past who was able to turn his life around would be ideal. Yet if you need them to be more creative, then you should get a speaker whose history speaks to that. While most motivational speakers can deliver good speeches to any audience, you will get optimal results if you can match the speaker to the topic.
Regardless of the particular topic, one important lesson that students generally learn after listening to a motivational speech is the power of words and how useful they can be in changing the perceptions of other people. This is important since it promotes the tendency to dialogue and discuss productively, as a way to solve disagreements and find solutions. Public speaking is also something that students have been known to develop a serious interest in, so you should be ready to cater for an influx into your debate clubs.
