Humor gives us smiles, laughter, and gaiety. Humor reveals the roses and hides the thorns. Humor makes our heavy burdens light and smooths the rough spots in our pathways. Humor endows us with the capacity to clarify the obscure, to simplify the complex, to deflate the pompous, to chastise the arrogant, to point a moral, and to adorn a tale. Read your daily newspaper with an eye for items that catch your fancy and that can be used to spice up a talk or article you are planning.
Television is filled with good material.
These give you access to all kinds of information and it just takes some practice to use them efficiently. Once your head is bulging with useful material, there remains admittedly the painful process of boiling it down into an interesting and memorable presentation. For most of us, the task unfortunately is very much like novelist Gene Fowler's description of writing. All you do is stare at a blank sheet of paper until drops of blood form on your forehead. But do persevere.
