“It is unrealistic to want to be happy all the time.”

“Happiness is a skill. It requires effort and time.”

“I do not claim to have attained optimum emotional well-being. Actually, I think that may be a lifetime goal. For me it’s an ongoing process that requires awareness, knowledge, and practice. I do know what good emotional health feels like, and that motivates me to keep at the practice.”

“People who are contented and serene sleep well. They fall asleep easily, stay asleep, and wake refreshed. Conversely, people who are anxious, stressed, or depressed do not sleep well, and chronic insomnia is strongly associated with mood disorders.

Most experts agree that sleep and mood are closely related, that healthy sleep can enhance emotional well-being, while insufficient quantity or quality of sleep can adversely affect it.”
