In the comment down below, I have written about the heuristics that I created for business starting timing. Some of them are the result of my own experience. - In my attempts, I was in an unsuitable country, in another attempt in a good country but not in a safe legal status (student visa), and I did not have enough business knowledge. -These also created a huge opportunity cost regarding my academic results and hindered my timeline to get a high-paying job that would satisfy other heuristics like an even better country, industry, and seed money.
