Take everything one day at a time.
It doesn’t matter how difficult your current situation is, you can get through it if you focus on what is happening at the present moment. In the movie Dinotopia, the instructor says, “You must face your fear if you are to overcome it. Fear is the future. There is no fear in the present. The present is only action and reaction.”
Forget the future and just get through each day, one day at a time. You can overcome anything that way.
