Aurelius

“True happiness is to enjoy the present, without anxious dependence upon the future, not to amuse ourselves with either hopes or fears but to rest satisfied with what we have, which is sufficient, for he that is so wants nothing. The greatest blessings of mankind are within us and within our reach. A wise man is content with his lot, whatever it may be, without wishing for what he has not.”
― Seneca

“People will choose unhappiness over uncertainty.”
― Timothy Ferriss, The 4-Hour Workweek

“The opposite of love is indifference, and the opposite of happiness is boredom.”
― Timothy Ferriss, The 4-Hour Workweek

“For all of the most important things, the timing always sucks. Waiting for a good time to quit your job? The stars will never align and the traffic lights of life will never all be green at the same time. The universe doesn't conspire against you, but it doesn't go out of its way to line up the pins either. Conditions are never perfect. "Someday" is a disease that will take your dreams to the grave with you. Pro and con lists are just as bad. If it's important to you and you want to do it "eventually," just do it and correct course along the way.”
― Timothy Ferriss, The 4-Hour Workweek
