I think it's both something you practice and also something you motivate yourself for. I had some entrepreneurial episodes as a kid, which I enjoyed and found some success in once or twice, but somehow forgot about in the teenage years. I started exploring the possibilities again, but I would say that I only got properly shocked into the mindset again after(surprise) getting hustled myself, in a bad way, and wanting to make up for it.

Knowing and relearning the "child's reality" is important to success, I think. It gets you past all the blind spots that derail businesses.
