Many adults in their 30s, 40s and 50s decide that they will change careers entirely. They may have spent the last 10-15 years in an unsatisfying career or job and during a critical period in their life they decide to get out of that dead end and follow their real passion. But a question that often holds these folks back from making that decision in their lives is that they think it is too late to change. The truth is, it is never too late. There are many further education raining centers available where you will be able to go to study regardless of your age.
Changing to an academic career
There is one group of adults who are coming from a technical or a manual background, but at some point during their career they have hit a wall when it comes to progression. They are not eligible to apply for a higher level position because they do not have a requisite academic degree in their background. In this case it is possible to go back to school part time to complete a postgraduate degree such as a Masters, which will grant them the ability to apply for higher jobs in their company.
This type of change to an academic degree from a technical background requires a different set of skills (particularly the ability to review literature and create pieces of writing to research) and these skills should be developed extensively before going onto the course to make it easier.
Going to a more manual career
Many adults who have spent several years working in a certain academic career often decide that they would rather be doing something different and more technical or manual. In this case, all that needs to be done is to complete some sort of training or certification in your free time while you work and then after you have gained your papers you would simply sit for the licensing exams so you can practice.
You need not necessarily come from an academic background for this. Anyone can at any point in time change their career and it is a complete myth that you have to be young to go to school. People of all ages and from all different walks of life are always going back to school and achieving their dreams and goals at different points in their lives.
