Your background is very good, which is very helpful for your future development. Since you don't want to live a plain life, I think the IT industry is a good choice. As we all know, IT industry is a highly competitive industry, but it also means there is a lot of room for development. People want to be dull all their lives, but they can't do without waves. If you choose online game development, you can learn C++, OpenGL and 3D game programming, which is very promising. Although the choice of direction is very important, I want to achieve what you said, "You can enter the industry at the age of 28, earn more than 100 thousand a year at the age of 30, and have your own career at the age of 35." This is inseparable from your future efforts. Come on! I hope your wish can come true!
