Much unhappiness comes from walking alone. When there are several, it's somewhat different. I must get into the habit of listening to others, for what the others say concerns me, too.
Actually, because of new technologies, my full studio is on my laptop. And I have a little keyboard in my bag. I can make everything I do come from my laptop. Even when I go to a big studio, all I do is to plug in my laptops. That's they way I do it.
