Just develop an eye for observation. It's very difficult for me to go through an entire day without noticing a new opportunity for a start-up. There are some very obvious behaviours you can look for to identify opportunity. Any time you see someone swearing at a product, make note. That product sucks, whoever is using it wishes they could switch to an alternative. There's an idea. Sometimes it won't be as obvious as swearing. Sometimes it is just "it's so annoying that I have to submit all my material to colleges. There should just be an API for college admissions." People talk about what they want constantly, you just have to tune in to hear it.
