A day in the life of corporate consultant William Melton, who moonlights as a writer and is co-author of "The Complete Idiot's Guide to Playing the Harmonica."

Who: William Melton

What: Corporate consultant whose "real passion" is writing. He is currently working on a stage musical about DeFord Bailey, a super star of the Grand Ole Opry in the 1920s and 1930s. Melton is the co-author of "The Complete Idiot's Guide to Playing the Harmonica."

Where: His home office is in the master suite of the two-bedroom condo in Harlem, NYC, where he and his wife live. On particularly stressful days, Melton says he may find someplace to work outside the home. Because his work is conducted via e-mail and telephone, Melton also is able to visit his mother in Kansas City four times a year, a month at a time.

When: Because he has clients around the world, Melton is often up before dawn to deal with something in Europe, or late at night for the Asian-Pacific region.
