You Suck at PowerPoint!
I spent last week working in a my company presentation to a big event. I long time ago I learned that knowing how to present your ideas worths more than your ideas in some cases.
When I score the highest grade in one of my Graduation class because of how I presented my software project, it didn’t work but I presented it as if it works, and to the teacher, an algorithmics teacher but also an entrepreneur, this was more important.
It made me realize how presentation is important, but I also know that it’s not everything, when it ends, the customer wants to see the software running. :)
