There are so many things I can be mad about in this life. At the same time, there are so many things that I should be thankful for, often as the result of my frustrations. For example:

FRUSTRATION: I struggle to pay my bills sometimes.
THANKFUL: I have a roof over my head, water and electricity.

FRUSTRATION: I need to get gas in my car.
THANKFUL: I have a car to get me where I need to go.

FRUSTRATION: I have to go into work early.
THANKFUL: I have a job to support my family.

FRUSTRATION: My kids are running wild throughout the house.
THANKFUL: I have been blessed to be a parent.

FRUSTRATION: My wife and I are in an argument.
THANKFUL: I have a wife who loves me and is willing to accept me even with my faults.

As you can see, even in the worst of times, there is always a blessing to be found.
