Much more important than adding years to your life, is to add life to your years. They can't call you an old dog as long as you are learning new tricks. Great opportunities come to those who make the most of small ones. When opportunity knocks, some people object to the noise. When the outlook is bad, try the up-look.
People can tell but never teach, until they practice what they preach.
All of us can bring pleasure in some way. Don't copy the behavior and customs of this world, but let God transform you into a new person by changing the way you think. Then you will know what God wants you to do, and you will know how good and pleasing and perfect his will really is.
