Peace comes from within. Do not seek it without. It can be argued that peace and happiness comes from the subjective internalised perspective of realizing things could be worse and being grateful they aren't. The alternative view that peace and happiness comes from the objective external perspective of having more and better things than at present, while important for growth, can be a never-ending source of jealousy, dissatisfaction and disappointment. A balance of the two, where people are grateful for what they have while striving for more seems the best blended perspective.
My brothers and sisters, do we remember to give thanks for the blessings we receive? Sincerely giving thanks not only helps us recognize our blessings, but it also unlocks the doors of heaven and helps us feel God's love.
If gratitude and esteem are good foundations of affection, Elizabeth's change of sentiment will be neither improbable nor faulty. But if otherwise--if regard springing from such sources is unreasonable or unnatural, in comparison of what is so often described as arising on a first interview with its object, and even before two words have been exchanged, nothing can be said in her defence, except that she had given somewhat of a trial to the latter method in her partiality for Wickham, and that its ill success might, perhaps, authorise her to seek the other less interesting mode of attachment.
The world breaks everyone or nearly everyone, of their childish illusions, assumptions and wishes, often painfully and afterwards due to the personal growth in practical experience, insight and the resulting wisdom many are strong at the broken places just like mended broken bones often are, and some people even have the great insight to be grateful for the purifying fire.
And some of your elders remember pleasures with regret like wrongs committed in drunkenness. But regret is the beclouding of the mind and not its chastisement. They should remember their pleasures with gratitude, as they would the harvest of a summer.
Summer is a prodigal of joy. The grass Swarms with delighted insects as I pass, And crowds of grasshoppers at every stride Jump out all ways with happiness their guide; And from my brushing feet moths flit away In safer places to pursue their play. In crowds they start. I marvel, well I may, To see such worlds of insects in the way, And more to see each thing, however small, Sharing joy's bounty that belongs to all. And here I gather, by the world forgot, Harvests of comfort from their happy mood, Feeling God's blessing dwells in every spot And nothing lives but owes him gratitude.
Whether we are in a pleasant or a painful state depends, finally, upon the kind of matter that pervades and engrosses our consciousness and what we compare it to - better and we envious and sad, worse and we feel grateful and happy.
