60-slides presentations is far too much. Here is the 'magic numbers' to creating the perfect presentation:

10/20/30

In a nutshell, entrepreneurs should use no more than

• 10 slides per presentation; keep the presentation to no more than
• 20 minutes in length; and use no less than a
• 30-point font for the slides.

All in all, it's a good, quick read on creating a presentation that won't bore your audience to death.
