Video lesson!
Today I had a thought. We are talking about investing a lot. And we are talking about trading a lot. But what we really need right now is a little bit off advice from real pros who know everything there is to know about these topic. So, I went on Youtube and searched for a perfect - brief yet informative - lesson on investing. 

And I am proud to present to you the result of my search! 

Enjoy your lesson! I hope it is going to give you a lot of useful info!
