Entrepreneurship is hard because: There's no Boss!
Think about it. As an employee, your agenda is set by your boss and your job is to execute it within the time limits. You exactly know what to do at what point of time. You know who to report to and the business is ready made for you - you don't have to search for clients.
If you are used to it; entrepreneurship is going to be very hard. You have to set your daily tasks, your short term & long term goals, you have to search for the clients and handle the operations and that too, execute within the time limits set by you.
