For becoming a professional, practicing and obtaining experience is the most effective way for some people. I partly agree with this idea. In fact, both ways have advantages depending on the job and the person. Experience is essential, it teaches useful skills, but education is still important. Without education, it can be hard to understand complex things at work.
To begin with, learning via experience helps people understand their work better. When people work in a real environment, they learn things that books can never teach. For example, for a chef, experience is the most important way of practicing. It helps them become more confident and independent. The same is true for other jobs as well. For instance, teachers, nurses and so on. By the way, it also teaches some skills such as teamwork and communication, which are as important as work talent.
At the same time, I believe education should not be overlooked. Education gives people the basic knowledge they need to start a career. Professions such as medicine, law, and programming require a sound academic foundation. For instance, a doctor needs to study medicine before treating patients. So, education builds a base, while experience helps to put it into practicing. Also, when people have both education and experience, they usually do their jobs better and feel more self-confident.
To sum up, I believe both education and experience are essential for becoming a successful professional. Experience teaches real-life skills, and education gives the necessary foundation to use those skills effectively. That is why depending on only education or only experience might not be enough for some jobs.
