Freelancing has been there for a long time, some claim that it won’t get your a living, but I doubt that. Considering the advantages of working as a freelancer, a lot of people are switching from full time to freelancing.
The reason I take up freelancing is because:
Flexible Working hours
The first thing came into my mind was the time on my hand. If I have any appointment at 10am on Monday morning, I can easily re-schedule my job without needed to get permission from my boss.
Cut off extra expenses
My fuel and road toll are the things that I concern. Imagine paying back and fore everyday with my own fuel when I can now wake up and in my office 
Be my own boss
I would say the flexibility when working. I don’t have to pass anything from my senior, or some a photographer to choose the photos, I don’t even need to wait for my boss to say “ok”, all by myself
My own working environment
I still remember my previous boss, who nagged me about taking off my shoe while on my desk. I mean, I am on my desk and I can’t take off my shoe to let me feet feel more comfortable? Idiot right? Now I get to choose my own style, my style? A short pant, no top, no shoe and a fan
No more certificate collection
This is the thing most old folks don’t understand. How can a job interview need no certificate? Well, design field doesn’t require much certificate, but an award winning certificate will surely get you on top fast. I don’t need to sit for GMAT prep to qualify as a freelancer.
At any time when I want to have a short vacation outside my house or state, I can easily pack up and schedule the rest of my job and go. No more letter to be approve or all sort of waiting. However, some people still thinking that working freelancing is not so practical, because the income is not fixed, which may result a month without a salary. But hey, it is the hard work you put in to get the comfortable of yourself
