Although I planned to abandon cartooning once my practice was successful, I didn't do so because every day in this unique and wonderful profession sparked more cartoon ideas. I still have a drawer filled with hundreds of notes on cartoon themes. It has been a joy to be able to bring smiles to my colleagues all over the world.
