Great thoughts cannot remain silent. They are born to scream!

Pessimism and hopelessness are two assassins that have been hired by very ourselves to kill ourselves!

In old age, mirror is not a friend!

Mankind has one great habit, a bad habit: To create rules on behalf of God! Unless A God appears on the sky and says 'Here are the rules,' do not take any rule serious! Remember that in this universe, there is no port that you can take refuge apart from the reason and the science!

Days passing with discovery are the days of real happiness.

Great passions may either bring great victories or great sorrows! In both cases, it is always a great privilege to have great passions!

Spend time for yourself, walk in solitude, refresh your mind and body so that you can spend time for others and walk with them! Spend time for yourself!
