The greatest things in life are indeed free.
Does anything else really matter in the great picture of our lives? If there is something other than freedom that has a greater impact in our lives, what is it?
Without that basic human right all else cannot be obtained.
The price of freedom is always paid for. You pay for it yourself or someone else pays for you. Either way, that debt gets paid.
So, make sure you're square before you use the free services afforded to you.
Know the value of the price paid before you open your mouth.
