There is actually very little reason to concern ourselves with that which is outside of our sphere of influence.
At best, doing so will cause us to worry.
Worry is an easy trap to fall into, after all.
There are an infinite number of possibilities for the future.
If we take the time and energy to consider all of them, we will surely go mad.
Worse than worry, however, is anger.
Both worry and anger have the power to destroy us from the inside out, but anger will do so quickly, violently, and with no remorse.
To give this power to circumstances over which we have no influence is not only self destructive, but it is a waste of our most valuable commodity, our time.
We will not get back the time that we give away.
Why would we give it away to that which we cannot change?
