To find out what happens to a system when you interfere with it you have to interfere with it (not just passively observe it).

All models are wrong, but some are useful.

All models are approximations. Essentially, all models are wrong, but some are useful. However, the approximate nature of the model must always be borne in mind.

Statisticians, like artists, have the bad habit of falling in love with their models.

Remember that all models are wrong; the practical question is how wrong do they have to be to not be useful.

The only way to know how a complex system will behave-after you modify it-is to modify it and see how it behaves.

Just as the ability to devise simple but evocative models is the signature of the great scientist so overelaboration and overparameterization is often the mark of mediocrity.

Discovering the unexpected is more important than confirming the known.

The business of the statistician is to catalyze the scientific learning process.

The management system which makes only a pretense of valuing employee involvement and encouraging employee empowerment merely breeds cynicism.

Management must provide employees with tools that will enable them to do their jobs better, and with encouragement to use these tools. In particular, they must collect data.

You will realize one day that all the money in the world cannot buy you happiness. Nor can it make you a person of good character.

Initiative is doing the right thing without being told.

I want to be around these positive, expressive people who are doing something different and who also want to get the hell out of there and don't want to be around basic human bullshit.

He that displays too often his wife and his wallet is in danger of having both of them borrowed.

I wouldn't want to be ideological about it but I think of it as being the best way to approach this kind of playing. I don't think it works in other music, other kinds of playing.

I took it upon myself to be more aggressive. I wanted the ball. Coach gave me the ball and I just tried to attack (and) make plays, just take it to the rim and see what happens.

You are responsible for what you have done and the people whom you have influenced.

Waiting makes me restless. When I'm ready, I'm ready.

The most interesting ideas definitely come at night.

In the brush doing what it is doing, it will stumble on what one could not do by oneself.
