Oil painting

I have experimented oil painting in the past, and I realized some works, but I never felt it necessary to my art. It is a technique that requires a great expenditure of time, very laborious even in the phases of preparation and maintenance of the tools (brushes, spatulas, palette, etc.). I have a direct nature and when I paint I cannot afford to wait for the long drying times of the oil in order to continue my work: in the meantime I would exhaust my tension.
