Taken from Seneca's letters:
"Just as the same chain fastens the prisoner and the soldier who guards him, so hope and fear, dissimilar as they are, keep step together; fear follows hope."
"The chief cause of both these ills is that WE DO NO ADAPT OURSELVES TO THE PRESENT, but send our though a long way ahead"
"Many of our blessings bring bane to us; for memory recalls the tortures of fear, while foresight anticipates them. The present alone can make no man wretched."
Hope and fear are emotions. Very powerful emotions, but still only emotions. Personal action that is fueled by either can have severe outcomes. Outcomes that are unpredictable.
The present moment and present action taken has no probability of outcome because it is not bounded by time. It is true in this moment.
Fear is the anticipation of the future, hope is the reaction to the past.
