When you are starting a business you will not have all the facts you would like to in order to be risk free when making decisions. You have to get comfortable with taking risks, you will fail but you will also succeed. There's no way around it, barely anyone has a perfect path carved out right in front of them when starting a business. You have to pave your own way. Even if you listen to mentors and people that have gone before, you will still have to curate your own path. Develop your instinct and patience!
