How on earth were those people able to create such amazing things? Will I ever be able to create something that brilliant someday? What should I even make? I have so many more tools than they did, even LLMs. Where can I learn the ideas and skills they had?
Find an itch, then scratch it. If many people have the same itch and can use your solution, you win.
Simple as that.
Find a problem and work on a solution for 20+ years.
Start fixing the unfixable and doing the undoable things ;)
The smart path: Find good mentors (and return the favor); use LLMs not to do the work but to help you learn and exercise your brain: make them test you, using something aking to teacher/Socratic method, make mistakes and get the mentor/LLM to review in a way you figure out the answer.
