An Entrepreneur needs to learn a lot, while I always believe that an experienced person can always conduct a better business than a fresh one but learning mostly depends on these 2 things instead of size of organisation. (1) Your Role in organisation : you should be at the place where you get enough exposure to learn new things (2) Your desire to learn : The person who is happy in a 9 to 5 job can never learn the things which don't fall in his/her JD so if you really want to become a good entrepreneur, you should be ready to do as much work as you can do to learn new things
