The video is from 2000, but like all of his advice its timeless. One the things mentioned in the talk that really stuck out in my mind is the following in reference to the failure of Long Term Capital:

 

 

To make money they didnt have and didnt need they risked what they did have and what they did need.

 

He goes on to make an example with someone who has 100 million dollars. If this person can earn 10% a year on his 100 million dollars without leverage at almost no risk, or take some risk and leverage his 100 million dollars to make a 20% return this person would be crazy to risk losing their 100 million for an additional 10%. Especially because they already have 100 million bucks, how is the additional 10% going to make their life that much better? It isn’t it. But the downside if they loose is obvious, they no longer have any money.

The google video link above is for the whole 1 hour talk, its also on youtube broken up in smaller chunks.
