If you are a freelancer, every day is an adventure. The very nature of the work — finding your own clients, meeting their ever-varied needs and constantly learning new skills — make being a freelancer something that's not for the faint of heart. The key to any adventure's success is being prepared. What tools will you need to do your job each day? What's your hour-by-hour plan for the day tomorrow? How much money do you need to earn each week to meet your monthly goal?
All of these questions and a hundred more should be asked and answered before you jump into freelancing. And once you're doing it full-time, keep asking them.
You can never be too prepared for an adventure.
