Generate means to produce or create. If you want to generate really high-level ideas, you should let your mind roam freely.
Generate as well as other similar words such as generation and genesis come from a Greek word meaning "origin" or "creation." Let's say you have two siblings. In that case, your parents' marriage has generated three children. In a hydroelectric power plant, water generates power. And you can get a paper route or babysit if you're looking to generate a little income.
