Game Dev where to go

I want to become a game. Dev. I've watched tried and even made my first game tutored by brackeys which is a cube dodge game. I felt very happy and successful, but what to do to develop rather than buy courses that cost a lot of money. I have experience with unity, but I still could not dive often despite my passion for game development. People could have the same problems as mine. Suggest something to me Also coding is not really a problem. I was inspired by many projects that tried and failed them, they were even abandoned before even 25%. I know the benefits of starting small and staying simple, which I learned from the additional credits of the yt channel. But you want to learn stuff that I do not know and that too, while I work in small projects for you or for others with the sole purpose of acquiring knowledge and skills. the cycle continues.I want some help and inspiration to create great content
