Let none find fault with others; let none see the omissions and commissions of others. But let one see one's own acts, done and undone.

To be idle is a short road to death and to be diligent is a way of life; foolish people are idle, wise people are diligent.

He who lives with his senses well controlled, moderate in his food and drink, he will not be overthrown, any more than the wind throws down a rocky mountain.

Fashion your life as a garland of beautiful deeds.

Abstain from all sinful, unwholesome actions, perform only pious wholesome ones, purify the mind; this is the teaching of enlightened ones

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.
