It’s fairly easy to sound credible and confident when making a presentation, writes Darren Menabney in Three Things You Really Need To Stop Saying In Presentations. Unfortunately, it’s just as easy to undermine your authority and send the wrong message:

“I know the writing is too small” or “it’s really busy,” sabotages your presentation in two ways. First, it declares that you didn’t do your job; you created slides that are unclear and hard to understand. […] But the bigger mistake is that you’re admitting you know that you created subpar content, but you decided to inflict it on your audience anyway. How should that make them feel?

Read the post, then follow Menabney’s advice. Stop shooting yourself in the foot when delivering presentations. And start projecting more confidence and credibility. You’ll be glad you did.
