The wise old greek philosopher, Heraclitus, said something along the lines of "the only certainty in life is change" and this is one philosophical argument that is impossible to argue.
Many people believe that life is what happens while you are busy making other plans. I have often felt discouraged becuase things don't go the way I have thought they should. I know I am not the only one.
It is safe to say that we cannot control all the events in our lives, but what we can control is the values we keep and the thoughts we have. Our values influence our perspectives and help reduce anxiety and fear. Being intentional about our values for the specific season we are in will give you such stability and certainty even amidst the most uncertain of seasons - a perspective I am currently cultivating.
When we make decisions and choices out of a place of certainty, according to values that we have been intentional with, anxiety is dramatically reduced and we have no space for regret if the choice doesn't turn out the way we thought it would - instead we are able to respond with more choices that reflect hope and not fear.
