"Nostalgia is also a dangerous form of comparison. Think about how often we compare our lives to a memory that nostalgia has so completely edited that it never really existed."

Next Quote

You must purge yourself before finding faults in others. When you see a mistake in somebody else, try to find if you are making the same mistake. This is the way to take judgment and to turn it into improvement. Do not look at others' bodies with envy or with superiority. All people are born with different constitutions. Never compare with others. Each one's capacities are a function of his or her internal strength. Know your capacities and continually improve upon them.
