If you want to be extra paranoid, sit down and make a list of everything you need to do to start a small software company besides write code. Stuff like, find co-founders, identify the customers for the product you want to create, figure out your business model (direct sales? support? freemium? ads?), run numbers on your business model (how successful would you have to be to turn a profit?), how do you file taxes as a business (in many countries the process is different), how will you recruit employees, remote, developers, sales, do you need to incorporate immediately, how do you do that, is there a payroll/benefits provider you should sign up with, how much does that cost, where can you get angel and VC funding for your company, are there any conferences you should go to to identify customers or competitors, etc etc etc. There's a lot of stuff to do and learn to start a successful company besides producing you MVP. Get them out of the way now and focus on honing your programming skills. And if you don't like thinking about taxes and employee benefits and balancing what you can afford against what you want to provide, well, you might consider just working at a startup instead of starting one.
