One option: get a part time job in an interesting industry.
I discovered this by getting a contract (few days a month) doing onsite work for a small/medium size organization. I asked lots of questions about things that I perceived as broken and found out what processes and software they hated. Then I worked on a prototype (evenings, for fun) and showed it to them. Now a year or so later that organization is my first customer for a SaaS I saw that they needed.
Also, make friends with other vendors while you're there. A company that already serves that industry can give valuable feedback and even market your app to their other clients if it integrates well with their solution.
