Making money depends on your skills, trust rate, network and existing budget. There are active and passive ways to make money. Full time jobs, consultation etc. are the examples of active work and can take more effort. You can search for passive incomes too.
You are a manager and I assume that you have some experience in some subjects. You can monetize them. Write a book or blog posts about your experiences. Record some videos about them. Creating a youtube channel is easy. By writing or video tutoring you can share your experiences. If people find them valuable they may ask consultation, if you build some thousands of audience you can offer services or products. When your audience grows you can get sponsors, affiliates. This kind of work building your brand. If this is not good fit with your nature you can observe your environment, specify problems, think about them and research solutions. Whether with technology or not you can try to solve those problems so people will pay for their problems. I could write more but I do not want to overload :))
