Our immediate worldview of time affects our value of the past, present, and future. Visualizations were created to illustrate how time relates to our emotions and effects optimism verses negativity. Do you have a bright, joyful future? Is each day better than the last? How much does your view of time affect your emotions or vice versa? These are some of the questions the visuals ask. The accompanying terminology for "time-perspective" relating to positive and negative viewpoints is credited to Philip Zimbardo, co-auther of The Time Paradox.
