You have an interesting point and I've been feeling the same way for some time. I've been feeling less and less satisfied with just consuming content that others have made and have been taking steps towards creating my own stuff. Right now that's just some hobby coding for a new project, but I have to say it's INCREDIBLY satisfying once you get going.
But... as you said, you need to be motivated. The first step is finding out how to become motivated. Creating something requires far more effort than just consuming something made by someone else, and so it's hardly surprising we are a culture of consumers. Being the time-poor, tired, overworked people we are, there's little motivation at the end of the day to expend effort on a task that may or may not even produce something good at the end. In my case, the allure of gaming made working on my own projects not even an option, because it's easier to chill and play.
However, even if my current project doesn't pan out, the journey is satisfying enough. And I think it's important to know that a balance can be achieved between creating and consuming. All-consuming, barely any creating (except perhaps the mandated stuff for work) eventually pushed me towards a better, healthier outcome.
