The best step is to look at things in your everyday life, and figure out what are the pain points, or what can run smoother. Your best chance to get a business idea isn't from something that you know nothing about (for instance, I'm sure there are great ideas to start businesses in aircraft production, but I know nothing about that industry, so I wouldn't know). What's going on in your world that seems like it could be easier? Think about everything you do on a daily basis and look for improvements. Then think through your head what those might look like.
