How to be confident?

There are eight billion people in this world and all were small child ones in their life so why to be shy when talking with them, every single of us are like a small ant lying in corner of the universe. Watch this video:

Look how small we're in comparison to this giant cosmic web. Just one big steroid and you'll be dead So why to be shy when everyone is just normal and human like you.  

Be confident and live your life to the fullest!

And Every time you need confidence, and be less anxious when giving interview or talking with people just think about this video, think how small we're.

Tip :- I have also found that having the bad mood can also boosts confidence because after being pissed off and extremely angry, you'll be like I don't give shit to anyone. So, you can also try this method before any speech or interview, it would not affect your performance that much rather you would not care about the interviewer and makes you "just be you"!
