“Hope is the power of being cheerful in circumstances that we know to be desperate.” — G.K. Chesterton
Hope is what we have. It is the one thing oppressive regimes try to take away from the people so that they will rely on the rulers in power. This was the case in the USSR, currently the CCP and many other examples in history. If you have hope, you can make it through your trying times.
Who you put your hope in also can change the course of your life, your attitude and your day.
