“I may give out, but I won’t give up!” I kept reading that sign on the wall as I struggled through the physical therapy required of my new knee.

Since last year’s knee replacement went so well, I got another one last month. Now I have two knees that are much younger than the rest of me is.

I added another sign: “A smooth sea never made a skillful mariner.” A skillful sailor is one who has been through the storms and has learned not only to manage, but to be victorious.

The postal rate climbed 2 cents last month. The postal service introduced a “forever” stamp which locks in the 41-cent rate for all eternity. Measured by the U.S. Consumer Price Index, stamps are actually getting cheaper.

Nathaniel Rich, an editor at The Paris Review, writes that the 20-cent stamp of 1981 would be equivalent to 45-cents in today’s dollars - which makes today’s rate 10 percent cheaper than it was 26 years ago. I will keep that in mind next time I start to complain about the cost of mailing a letter.

A lot happened while I was away. British Prime Minister Tony Blair announced he will step down next month. After hearing this, comedian Conan O’Brien said President George W. Bush said: “That’s a shame. He’s the only world leader who took the time to learn English.”

The last time the Queen of England was in the United States was 1991. And an awful lot has changed since 1991. David Letterman noted: “The last time she was here … President Bush was fighting a war in Iraq.”

Immigration has become an even greater issue these weeks. All the candidates for president are working on the best way to solve the problem. It might help if they went back to the Senate jobs they were elected to and work with the House and White House for some answers.

Jay Leno quips that proponents say we need immigrants from Mexico to take the jobs Americans don’t want to do. Now, don’t confuse that with India, where the people are taking the jobs Americans want to do. That’s totally different.

Ralph Waldo Emerson wisely said to see every new day as the best day of the year. “Finish every day and be done with it. You have done what you could. Some blunders and absurdities, no doubt, have crept in. Forget them as soon as you can; tomorrow is a new day. Begin it well and serenely with too high a spirit to hear with your old nonsense. This new day is too dear, with it’s hopes and invitations, to waste a moment on the yesterdays.”

I read somewhere that when the door to opportunity closes, another opens, but often we look so long at the closed door that we do not see the one which has been opened for us.

Even if you are on the right track, you will get run over if you just sit there. Corny? (Corny is a 1940s phrase meaning “out of date.”) All this positive thinking stuff may be out of date, but it still makes for a better life. As for me and my knees, I may give out, but I won’t give up.
