There is not always a roadmap for everything. What works for someone may or may not work for you. The roadmaps are definitely useful when learning a tech stack. But, when it comes to creativity there is no such thing called as a roadmap. Your experiences make you who you are and how your perspective is formed.
Experiences can be monetized. But, very few people do that. Because, I find that they are all following the roadmap of the people who are around them or from the people whom they find are the best. But, exploring our understanding and getting to know people from across the globe can significantly change your mindset. So, the content you watch, articles and books that you read all matters. They all show the results in the long run. I have experienced them and one day you will too. These in turn create your own roadmap.
