Artist & Illustrators magazine asked Picasso's grandson how many works his grandfather created. The answer:
"It is quite difficult to answer but we are almost able to say that since he was very young he made 2 or 3 works every day. But in his personal collection there were 2000 paintings, 12,000 drawings, 300 sculptures, 4000 ceramics, a few thousand print objects. His attitude was if you want to do something, just do it."
And that's what we can learn from Picasso.
