“The mind that is anxious about future events is miserable.”

“We should not fret for what is past, nor should we be anxious about the future; men of discernment deal only with the present moment”

“Reality is not a function of the event as event, but of the relationship of that event to past, and future, events.”

“Write to amuse? What an appalling suggestion! I write to make people anxious and miserable and to worsen their indigestion.”

“You are so anxious about the future that you do not enjoy the present. You therefore do not live in the present or the future. You live as if you are never going to die, and then die having never really lived.”

“...not all encounters with the world affect the mind equally. Studies have demonstrated that if the brain appraises an event as "meaningful," it will be more likely to be recalled in the future.”
