Pablo Picasso was one of the most prolific and influential artists of the 20th century. He produced over 13,500 paintings as well as thousands of prints, engravings, and sculptures over his lifetime. Picasso spearheaded several major art movements including the Blue Period, Rose Period, and Cubism. However, his personal life was turbulent and he lacked respect for others at times. True excellence is defined not by competition with others but by habitually improving oneself. It involves developing the right attitudes, skills, and knowledge over time.
