Of all the components of a good night’s sleep, dreams seem to be least within our control. In dreams, a window opens into a world where logic is suspended and dead people speak. A century ago, Freud formulated his revolutionary theory that dreams were the disguised shadows of our unconscious desires and fears; by the late 1970s, neurologists had switched to thinking of them as just “mental noise” -- the random byproducts of the neural-repair work that goes on during sleep. Now researchers suspect that dreams are part of the mind’s emotional thermostat, regulating moods while the brain is “off-line.” And one leading authority says that these intensely powerful mental events can be not only harnessed but actually brought under conscious control, to help us sleep and feel better, “It’s your dream,” says Rosalind Cartwright, chair of psychology at Chicago’s Medical Center. “If you don’t like it, change it.”

在决定成功人生的诸多要素中，乐观的态度看似最难培养。在悲观者的世界里，开怀大笑是一种奢侈，对失败的畏惧总是萦绕心头。过去，心理学家坚信，一些人生而悲观。而今，研究者们转而认为悲观是可控的——通过降低欲望就会获取更多愉悦；专注于任务，不要过于患得患失，就会减少恐惧。
Of all the traits leading to a successful life, optimism seems least possible to be fostered. For a pessimistic person, a window opens into a world where laughter is a luxury and the fear of failure haunts without any break. In the past, psychologists insisted that some individuals were born to be pessimistic. Now, however, researchers switch to thinking of pessimism as controllable — one can acquire more delight by limiting desires and sense less fear by focusing on tasks rather than the possibility of failure.
