topic presentation

It's great good Mohit! Public speaking, presentation boost up individual morale & open gates to network.

My mantra for good presentation is:
- KISS : Keep it simple and short . So your PPT shouldn't not look like Newspaper, I mean that much cluttered. It should precise & carry relevant information 
- UI matters: PPT font, colors, bold, italics these things are very important when you're presenting on screen. So, if you can put your PPT on projector before actual demo and see how it looks like, it should be good rehearsal.
- Look for references on your topic: look at slideshare.net for your topic, i'm sure someone has posted some stuff, so get reference from there and see how matter is arranged

Demo mantra:
- While doing public speaking, speak like you're narrating a story. Like story teller and conveying your topic
- keep audience engaged; so audience shouldn't be only listerner, and you should try to enage with them via some intermittent questions and knowing their opinion. It should be interactive
