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.

When we have sampled much and have wandered far and have seen how fleeting and sometimes superficial a lot of the world is, our gratitude grows for the privilege of being part of something we can count on-home and family and the loyalty of loved ones.

We should wipe two words from our vocabulary: gratitude and charity. In real life, help is given out of friendship, or it is not valued; it is received from the hand of friendship, or it is resented.
