Achieving the biggest career goal in your 20s and 30s: Insights from a boss who has managed 100 people.

Christine Cruzvergara is comfortable addressing large groups, whether they consist of college students or CEOs.

Handshake's chief education strategy officer, Cruzvergara, has over a decade of experience speaking on national and international stages, including top-tier conferences, higher education and policy events, boardrooms, and commencements.

When her direct reports express a desire to improve their public speaking skills, she offers them a few tips to help them learn the skill.

She states that a significant objective among reports in their mid- to late-20s and early 30s is achieving a large goal.

Cruzvergara states that she frequently receives feedback from individuals expressing a desire to enhance their executive presence, specifically in terms of communicating with senior leaders, presenting effectively in meetings, and creating materials that resonate with their audience.

She imparts the same set of tips to all her employees who aspire to improve their public speaking skills.

Mirror your communication style with company VIPs

The effectiveness of your public speaking skills is largely influenced by the communication style of senior leaders in your organization, according to Cruzvergara.

What are the communication traits and characteristics of your CEO, COO, VP, or president? How do they typically focus their communication?

Is this person a concise speaker? Do they tend to write brief emails? Are they passionate about context? Do they frequently use data in their communication?

According to Cruzvergara, analyzing how your company's VIPs communicate can reveal their preferred way of consuming information and what they prioritize.

After understanding that, you can begin to develop your own messaging strategy, whether it's written or verbal.

Know when to deliver the 'punchline' versus the context

Cruzvergara describes his experience at Handshake by stating that he shares with his direct reports that the company's leadership prefers punchlines over context.

When speaking with our CEO, it's important to answer his questions directly in the first sentence, and then provide context.

"If you delay delivering the main point, you'll lose your audience, regardless of the quality of the information you provide."

Seeking guidance from your manager while preparing a presentation can help you deliver information in a way that decision-makers will find most effective, thereby enhancing your executive presence and securing buy-in from key stakeholders.

Stay confident and humble

Finally, Cruzvergara says that with practice comes confidence.

While people possess the necessary information and skills to gather data, it is the way they present it that requires improvement.

To improve your public speaking skills, you can start with smaller meetings and gradually progress to larger ones. Seek feedback from your manager and others to identify areas for improvement.

Cruzvergara says that practicing can help you become more comfortable and overcome nervous habits, such as using filler words or hedging your statements.

She emphasizes the importance of being both humble and confident.
