"É preciso coragem para ser diferente e muita competência para fazer a diferença"

Last will - first day

Learn everyday
Today's state of knowledge is just transitional
Do not believe overmuch in authorities or teachers
Everything which looks simple is probably wrong and much more complex
Dare to go against the flow and have new ideas (think outside the box)
Always be aware that life is a historical process
Enjoy life and work
