What's the hardest part about freelancing that no one talks about?

[Btaliat]

People don't really focus on the hardest part of freelancing. Others have had the belief that freelancing is a wy of making money without doing much work. That's not it. Freelancing as it is requires only those that are dedicated and even serious to get money. There are some instances where freelancers can stay months without having any clients. Freelancing is a task that needs mastery before it can be done successfully. What do you think?
