Developing Trading Strategies
Sometimes it takes several years to recognize the obvious.
The simpler it looks, the more problems it hides.

Buying Stocks
If anything can go wrong, it will.
If anything can't go wrong, it will.
If you know something can go wrong, and take due precautions against it, something else will go wrong.
You will never run out of things that can go wrong.
Failure is the opportunity to begin again more intelligently.
The less you do, the less can go wrong.
You can never tell which way the train will go by looking at the track.
Always assume that your assumption is invalid.

Selling Stocks
You never know how soon it is too late.
When things go wrong, don't go with them.
If you are in a hole, stop digging.

Following Trading Strategies
Being punctual means only that your mistake will be made on time.
A good place to start from is where you are.
To learn from you mistakes, you must realize that you are making mistakes.
Experience is what causes you to make new mistakes instead of old ones.
The best defense against logic is ignorance.
If you enjoy what you are doing, you are probably wrong.

About Diversification
Things go wrong all at once, but things go right gradually.

If you don't know the answer, someone will ask the question.
You don't have to explain something you never said.
If you want to make enemies, try to change something.
Be kind to everyone you talk with. You never know who's going to be on the jury.
Never be too right too often.
The only changes that are easily adopted are changes for the worse.
The less you have to do, the slower you do it.
Always do exactly what your boss would do if he knew what he was talking about.
The e-mail never comes when you have nothing to do. The less you say, the less you have to retract.
