A wise man is content with his lot, whatever it may be, without wishing for what he has not...
This is the only way to find true satisfaction and appreciate what we have. Only when we appreciate what we have can we see it as a blessing. I am always grateful each day for life, for air, for good health most especially. These things seem so free but many wish they have it.
Really speaking @zizymena, it is those "free" things, that are worth the most in our lives :)
