I believe that if a leader knows what they are doing then there is not much difference what industry they are in, they will continually find success in it if they are smart and know the tactics and hard work it takes to get a business running and succeeding. However, it is said that some industries are more difficult than others and I do believe that to some extent. I have heard that restaurants are one of the worst choices for making money which is why it should mostly be done out of passion as a priority and money only second. Also, toys and retail in general, especially when the product is new and requires customer education since it takes a lot of capital to market such information. What industries do you think are the most difficult to break into or succeed in?
