Most people will take some sort of art class while they are at school and there are a lot of benefits to doing this. However after they leave elementary school most people will never again study art; this is a shame since there are a lot of advantages to taking an art class. Even if you are not planning to become a professional artist you can still benefit from taking an art education.
The most obvious reason that you would want to get an art education is simply that you have an interest in art. Most people have some interest in art and would like to be able to improve their skills. This does not require that you pursue a fulltime art education, there are lots of standalone courses that you can take that are aimed at people who are taking them for personal interest. Of course if you really do love art and you have an aptitude for it you may well want to take a fulltime course so that you can pursue a career in the field.
While it is possible to become an artist without getting an education in the field you will probably find that it helps to get one. For starters an art education will make you a better artist. Many people have artistic skills but they do not have the technical skills or the discipline that is necessary to be a professional artist. Getting an art education can help to focus this. In addition an art education will give you more credibility when you set out to find a job as an artist.
Another good reason to get an art education is that it can really help you out if your career as an artist does not work out. There are lots of people who want to be artists but only a relatively small percentage of them will actually succeed. That does not mean however that your art education is wasted. There are lots of related careers like teaching art that can be pursued if you have a degree in art. Having something to fall back on will make it much easier to pursue your art career since you will not have to worry about what will happen if you don't make it.
One last reason that you would want to get an art education is that it can help you in a lot of areas of your life. For example taking art classes can help make you more creative which means that you will be able to come up with creative solutions to problems that you encounter, this is something that employers are always looking for. There are also lots of studies show that people who study art have more self confidence and do better in their studies in other fields.
