This is more commonly referred to as "self-improvement" or "self-help" (depending on if you think you're just improving yourself, or more specifically addressing something you consider to be a weakness or shortcoming.) It means developing your skills or learning new ones, and coming to a new understanding of a topic of interest.
You also might want to start by figuring out what role you want to be in, whether professionally or in hobbies. It's not clear if you want to be a problem solver or a creator. Having lots of aliases for what you mean isn't giving anyone clarity. Being a "maker" often means you have projects you work on because you're interested, and you want to tinker and build things. But a "creator" might be slightly different, as would a "creative." A "problem solver" in business is more likely someone that is called upon when there are problems. That's vastly different from being a "creator", "maker" or "creative."
In general, I think you're caught up in "programs" and buzz words. In my opinion, you need to take five steps back and think about what you really want to be doing and go from there.
