Speak Up and Succeed Day is celebrated on the fourth Tuesday of January each year in the United States. Established by speaker and author Mary-Ellen Drummond, the day emphasizes the importance of public speaking as a skill that can lead to success in both personal and professional life. It encourages individuals to challenge themselves by speaking up in public settings, thereby making their ideas and identities known to others. The observance highlights that effective communication can change minds and motivate people. Participants are urged to embrace opportunities to develop their public speaking abilities, recognizing it as a vital skill that has been valued since ancient times.
