Learn about marketing and sales. Talk to and connect with people. More importantly, listen to them first. Don't try to focus on ideas, rather train your mind to be aware of problems - big and small - around you. Take notes about problems you noticed and review those notes from time to time. Talking to people and noticing things will let you discover true opportunities while thinking about ideas for yourself is more like a gamble: You might fluke it but it'll really be down to sheer luck. A word about passion: Doing something you love is essential but don't limit yourself to something that you've determined to be passionate about early on. As with problems around you rather be open-minded and let passion come to you. There can be passion in the most unlikely places (I for one am quite passionate about creating boring enterprise software because there's plenty of improvement to be made in that area, particularly in terms of usability and UX)
