Here’s my advice: if you want to improve anything from your relationships to your career to a specific skill or tactic, get help. Ask your peers. Ask a mentor. Hire a teacher or coach. Get help from people who already know what you need to understand. But know that this type of improvement takes guts.
I believe my job isn’t to be “good enough”. Or to earn evaluations that are high enough that nobody is unhappy. My job is to absolutely rock an audience in a way that everybody congratulates my client for picking the perfect speaker. The speaker that they’ll never forget. The speaker that will make next year’s speaker look bad by comparison.
