Every failure is a step to success.

1 Remember to keep a clear head in difficult times. 2 There are two main human sins from which all the others derive: impatience and indolence. 3 The greatest souls are capable of the greatest vices as well as of the greatest virtues. 4 The material has to be created. 5 Every failure is a step to success. 6 Adversity is the first path to truth. 7 To doubt everything or to believe everything are two equally convenient solutions; both dispense with the necessity of reflection. 8 The wound is at her heart. 9 If you make a mistake and do not correct it, this is called a mistake. 10 People, often deceived by an illusive good, desire their own ruin. 11 A man who cannot command himself will always be a slave. 12 Force without wisdom falls of its own weight. 13 The worst enemy you can meet will always be yourself.
