Perhaps consider creating your own product as a "micropreneur": a mobile app, a SaaS service, a social media website, etc. Evenings/weekends at first, using your salary money for dev outsourcing and marketing. This kind of endeavor will feel very personal in the context of "ownership" and very hands-on in every respect. Make sure to read a couple of Product-Market-Fit books first (e.g., "Start Small, Stay Small" by Rob Walling), if you are not already familiar with the subject of business development.
