Experience teaches us that it is much easier to prevent an enemy from posting themselves than it is to dislodge them after they have got possession.

You learn from a conglomeration of the incredible past - whatever experience gotten in any way whatsoever.

With every experience, you alone are painting your own canvas, thought by thought, choice by choice.

Experience is never at fault; it is only your judgment that is in error in promising itself such results from experience as are not caused by our experiments. For having given a beginning, what follows from it must necessarily be a natural development of such a beginning, unless it has been subject to a contrary influence, while, if it is affected by any contrary influence, the result which ought to follow from the aforesaid beginning will be found to partake of this contrary influence in a greater or less degree in proportion as the said influence is more or less powerful than the aforesaid beginning.

Wrongly do men cry out against experience and with bitter re- proaches accuse her of deceitfulness. Let experience alone, and rather turn your complaints against your own ignorance, which causes you to be so carried away by your vain and insensate desires as to expect from experience things which are not within her power!

We should not look back unless it is to derive useful lessons from past errors, and for the purpose of profiting by dearly bought experience.
