It's great to have dreams and aspirations and goals and it's great to hear a story about someone who attained their dream through grit and determination and all that good stuff, but... the cold harsh truth is that it's simply not possible for everyone to live their dream. The world would not work without the worker bees to keep things working.
There are only a small number of premium jobs out there and a whole lot of people trying to get them. And sometimes they go to not the most qualified, but the best connected.
Starting your own business is a dream of a lot of people. Some are lucky and are able to be successful at it, Some flat out fail at it, and there are a bunch who are barely grinding out a living with it, not much better off than if they were working for someone else.
So while it is good to dream big, it is also good to keep some of your expectations grounded in reality and to have a backup plan in case things don't pan out the way you had hoped they would.
In other words, lock down that 9 to 5 first, so you can pay your bills, then go chase your dream job.
