Rather decide almost right than exactly wrong.
Johann Wolfgang von Goethe
Ingenious people start great works, diligent people finish them.
Leonardo da Vinci
The key to success is not information. It's people.
It is no drama, if the project doesn’t go according to plan. It is a drama, if the project manager doesn’t know anything about it.
I don’t sell future for instant success.
Werner von Siemens
The best executive is the one who has sense enough to pick good men to do what he wants done, and self-restraint to keep from meddling with them while they do it.
If one does not fail at times, then one has not challenged himself.
The errors which arise from the absence of facts are far more numerous and more durable than those which result from unsound reasoning respecting true data.
Many people are persistent in relation of the path they have taken, only few in concern of their goal.
No plan survives contact with reality. (Inspired by “No plan survives the first enemy contact”)
Helmuth von Moltke
