Charlotte Brontë said this quote

I believe - I daily find it proved - that we can get nothing in this world worth keeping, not so much as a principle or a conviction, except out of purifying flame, or through strengthening peril. We err; we fall; we are humbled - then we walk more carefully. We greedily eat and drink poison out of the gilded cup of vice, or from the beggar's wallet of avarice; we are sickened, degraded; everything good in us rebels against us; our souls rise bitterly indignant against our bodies; there is a period of civil war; if the soul has strength, it conquers and rules thereafter.
