Making sure that your skills are suitable to your job is somewhat of a continual process. For most jobs, the processes, and skills which are required are constantly changing, so you should know beforehand that continuing to educate yourself is an important part of any profession. For most jobs, this continual learning can take place while working through it, but in some instances, sacrificing your personal time to learn new skills may become necessary. This isn’t something which you should be wholly unappreciative about though, as the more qualifications that you can gain in a position, the greater your worth to the business, and any other potential employers. These added qualifications mean that you can consider demanding greater pay for your work, and if you didn’t have to pay for them, because your employers have, then even better for you.  Failing to continue to develop in multiple ways, can, not only limit, but also damage your professional future.
