American business schools promote MBA programmes by talking about a ROI or return on investment. This is a financial calculation telling you how quickly you’ll pay back your costs in time and money when you sign up for a course.
The assumption is your earning power will increase dramatically once you’ve graduated. Typically United States MBA graduates are financially ahead after three or so years.
You can’t always estimate of the value of work-related courses so directly. And anyway, learning extra skills isn’t just about money; you’ll gain extra understanding of your work, improve your confidence and find it easier to complete various tasks.
You might even enjoy life more.
Any extra skills you get will have some benefit in the workplace – even when the connection isn’t obvious. If you continue your education, you will be a better employee.
Think of it this way, you go for a job and there are two candidates. One has taken a string of courses in evenings and weekends, the other has done nothing. Who do you think is going to get the job?
