All writers get asked the question
"where do you get your ideas?" Even nobodies like me hear it. It's become a cliche among authors, to the point that Harlan Ellison started telling people that he writes to a
'fine Idea Service' in Schenectady, New York, which, for a modest fee, provides him with new ideas upon request.
But of course, the very question misunderstands how the brain works: ideas don't just descend from nowhere, there is no store of them sitting out there, untouched, just awaiting discovery. Ideas are forced into existence by sheer necessity. Whenever you wonder how someone 'became so creative', it might be beneficial to sit back and ask yourself what 'creativity' actually means.
To say that someone is creative means that they are capable of coming up with novel solutions to problems. When they are confronted with something that needs to be done, they find a workaround. This means that, in order for us to be creative, there must be some sort of conflict staring us in the face: there must be some conundrum that needs solving.
