Entrepreneurship is taking the unknown road, so you’ll always have the feeling you are experiencing of “am I on the right track”. Just keep doing you and don’t compare yourself to someone else’s journey. As long as you are growing on a regular basis, learning more and more, you’ll do just fine. Just keep with it and don’t second guess yourself. I’ve been doing this for 13 years and I still have this feeling.
