Earning a skill is more valuable than earning a job these days. Skills are your most valuable asset. They can help you qualify for jobs you want and get promoted to more advanced positions within your organization.

We have had many students, who have taken just Udemy courses, started a job as well as started freelancing with the skills they have learned.
