I abandoned surgery, I abandoned medicine. The only person I consulted was my wife when I said ‘Listen, next month, we’re not going to have a salary. On the contrary, we’re going to take all our savings and waste it on tuition fees.’ That’s it. That’s what I wanted.

Many times when I found myself at a personal crossroads – when I graduated from Hitotsubashi University and was unsure about whether I wanted to go into research or become a businessman, when I quit my job at the Industrial Bank of Japan (currently Mizuho Bank), when I founded Rakuten, when I tried to buy Tokyo Broadcasting System (TBS) – I always visited my dad in Kobe to ask his advice. Like my wife, my dad was a behind-the-scenes counselor to me.

But I need to show my work during the process. In the editing room, very often I invite friends and I do some test screenings with friends or people I know: editors, journalists sometimes. I ask them, Is it boring? Is it too long? What do you think?

I’m calling people like Simone Leigh, Cauleen Smith—people who have sold things—asking, “What does this look like? What is this process?”
