Wanit was born on August 9, 1949, in Bang Pla-ma district, Suphanburi. after some elementary schooling there, and later some vocational training, he enrolled at the Painting and Sculpture Faculty of Silpakorn University in Bangkok. Upon graduation, he went to work as an artist for the popular women's magazine Satri-sarn, and for theThai Farmer's Bank. Later in 1974, he went to study in California State University at Long Beach, where he gained an MA in print-making four years later. While in the United States, he began writing humorous sketches about life in California, sending them back for publication in various magazines in Bangkok. They proved enormously popular and were eventually collected and reissued in two volumes under the title Jodmay thung phuan (Letters to a Friend). Wanich had now found his metier as a witty, satirical, and often political, free-lance columnist. In the intervening years no less than eight further collections of articles and occasional pieces have appeared: Jodmay thung Mae Jamnian (Letter to Mae Jumnian); Phuan phu yu nai ban (Friends at Home); Pradiawdiaw thi jatturat daeng (A Moment in Red Square); Lo Yurop (Skirting Europe); Sonthana prasajon lae Kuay Jeng (Poor People's Conversation and Kuay Jeng); Sawatdee krab khun phu ying (Hello Ladies!); Rim rabiang (The Edge of the Veranda); and Soy jai sabay (Happy Alley). In addition, Wanich has produced a light, romantic novel called Khehat dao (Mansion in the Sky), 1983; a collection of short stories entitled Soy Diewkan (Same Alley); a volume of poetry; several excellent children's books; and two plays for television.
