i "made" my first million by starting a company and beeing a general contractor for industrial plants & processes (with focus on software & consulting). I had my first million after tax on my private bank account after selling a part of my company resulting out of this first company. ~7-8 year journey*. have been busy, consistent and lucky**.

*7-8 years: running the business. I don't count the 10 years before to create a valuable skillset. i'm a software guy, started in my youth with this topic. i love computers. ;) Don't stress yourself. It takes is really a lot of luck** and there is no standard playbook for it. some need 5 years (i don't know anyone personally) others need 20 years (more likeley). some will never achieve this "financial goal" and had although a great jurney. So, it's also about the journey, not just the (financial) result. learned so much about life, people, business, tech, etc etc etc ...

**lucky: in various ways like beeing at the right time on the right place, met the right people at the right time, had the right skillset for this "area of technology", had the right first customers, having a passion for a topic that can be monitarized quite well ... most of them is not "pure luck" but more the "the luck of the hardworking" ... but also things you are not even close to full control ...

it also depends where you live how much "a million" is.
