First impressions have a big impact on how others perceive you, so how you introduce yourself to others is extremely important. Many people call an introductory speech an elevator speech, because it should be succinct enough that you could introduce yourself and tell someone about your goals or interests in the time it takes to ride an elevator.  It may also be called an "icebreaker" speech, as it breaks the ice and lets others get to know you.  Consider your words carefully when you write a speech introducing yourself. Crafting a good self-introduction can either build or harm your credibility.
