A skill is an ability that may be acquired by a person. Skills are often unknown until they are learned, except for when learning a related skill. Acquiring skills is something you should strive to do all throughout life. When you build skills, you open your mind to new things and you exercise your brain in new ways. Learning to acquire new skills is a skill in itself.
Exploring careers is a normal part of life. We all get jobs that we think will satisfy us or at least pay the bills and then we are often met with disappointment. At that point, it is time to reevaluate the career path you want to be a part of in your life. Think about the aspects of your job that make you happy and the parts of your job that you could do without.
