In all my ventures this is the most asked question I get. I've been in those college dorm conversations about how to start a company - and while I'm not sure I understand the question completely my answer is that ideas are happening all the time. Every day new ideas flood in. It is focusing on something so hard that it fills the gaps in between your thoughts. Fills the moments when you are driving, standing in the shower or is there right before you fall asleep. When you are in this state the changes or adjustments you need to try pop into your mind - and if you write them down you have a chance to discover something!
