"You can exercise control over situations by your response to them," is a statement that came to me in prayer. Which is not to say we have control over economic forces, serious illnesses and wars, accidents and other catastrophes. But we can exercise control in how we respond.
Being aware and candid with ourselves, allows us to exercise self-control and apply ourselves most effectively. You can take self-protective actions and you can also take actions to protect others.
In addition, you can treat life as the brief and precious gift it is and enjoy each and every day, as you seek to find greater meaning, for this too is a form of exercising control over situations by your response to them. So is expressing your love to someone who most needs it.
