Why I became a freelancer

February 09, 2023

After working in the corporate world for 8 years, I decided to take a leap of faith and start my own freelance business. It was an intimidating decision, but it was ultimately the best choice for me. In this blog post, I’ll explain why I chose freelancing and what I have learned along the way.

There are several benefits to freelancing that made it an attractive option for me. The first is the flexibility that comes with being your own boss. As a freelancer, I get to decide when and where I work and how much work I take on at any given time. This freedom allows me to structure my day in a way that works best for me and my lifestyle.

“No matter how much experience you have, how many degrees you have, or how well-known you have become — there is always something new to learn. Don’t rest on your past experiences. If you do nothing to improve your skills, you won’t stay where you are.” ― Laura Spencer

Another benefit is the potential to make more money than a traditional job might offer. With freelancing, there are no set salaries or pay grades; instead, you can negotiate your rates with clients directly. This means that if you are willing to put in the extra effort and deliver top-notch results, you can maximize your earning potential. Additionally, many clients are willing to pay premium rates for specialized services or expertise that they cannot find anywhere else.

Finally, freelancing gives me an opportunity to explore different industries and fields of interest that may not have been available in a traditional job setting. Working as a freelancer has opened up new doors professionally as well as personally; it has allowed me to meet people from all over the world and learn about various cultures in ways that would have been impossible had I stayed within one company or industry.

All in all, deciding to become a freelancer was one of the best decisions I’ve ever made—and it’s one that many other professionals considering taking their career into their own hands should consider making too. Freelancing offers numerous advantages both professionally and personally, including increased flexibility, higher potential earnings, and access to different industries and roles than those found in traditional jobs. For these reasons—and many more—I strongly believe that becoming a freelancer is worth every bit of effort involved in getting started!
