Freelance graphic designers are the ones who are their own boss and can work from anywhere. They don't have any fixed office hours. They don't have to follow set rules, nor is there any limit to their earning potential.
To become a successful graphic designer, pick a name that stands out from the lot. Avoid using the word freelance in your name, and get your name registered to prevent others from using it.
Make sure you have a dedicated place to work from. Office space is okay, but most freelance graphic designers work from home. If you work from home, try to get a room dedicated to your business, without the interference of kids.
Keep the place clean and organized. Have enough room for a large desk, a filing cabinet, and a phone. Doing freelance graphic designing without having your own website is suicide. Pick a reliable website host, upload the site, and keep the site updated to convey professionalism in your work. Create a catchy and short domain name, and get it registered. Domain names only cost about $10 a year, depending on where you look.
As a freelance graphic designer, you are responsible for graphic designing, along with accounting, bookkeeping, janitorial duties, and marketing. It is you who have to answer phone calls and make appointments. You have to be very assertive to get your supplies to you on time. You can never be a person who can be pushed around.
Act and look like a professional at all times. When meeting clients, dress in formals or wear a clean dress. Always keep the client well informed and provide clear documentation as to what they can expect at the end of the designing process.
