2. Just for Today, I will be happy. This assumes that what Abraham Lincoln said is true, that “most folks are about as happy as they make up their minds to be.” Happiness is from within; it is not a matter of externals.
I have now reigned about fifty years in victory or peace, beloved by my subjects, dreaded by my enemies, and respected by my allies. Riches and honours, power and pleasure, have waited on my call, nor does any earthly blessing appear to have been wanting for my felicity. In this situation, I have diligently numbered the days of pure and genuine happiness which have befallen to my lot. They amount to fourteen: O man! Place not thy confidence in this present world.
