Is this field growing enough so there is room for someone like me ?

The insurance industry is growing and offers a multitude of different types of careers.  There is literally something for everybody in this field and there are an abundance of training and education options.  It's also a worldwide industry, so your opportunities are near endless.

Business is comprised of the creation, production and selling of goods and services that meet the needs of others. The field of business will grow and exist as new technologies, new processes, new global demands, new individual needs seek out products and services to enhance careers, health, education, safety as well as quality of life.

Industries are continuously created, emerge, experience rapid growth while others cease to grow as they can no longer compete. In my teen years, television was in its infancy-facsimile machines were unknown, personal computers were non existent, home phone ownership was unheard of, super markets did not exist, indoor malls had not been created, drugs had not been yet invented to address many of diseases we no longer see today. There was no internet. DNA was unknown.

In the future, artificial intelligence will create new, amazing industries. Bio-engineering will permit the development of drugs to prevent diseases from attacking us. Intergallic flight will be possible and the material resources from other planets and asteroids will create totally new industries.

Entrepreneurs, who can visualize the practical application of these and other events as well as discoveries, will create products and services we are unable today to contemplate.

Yes, business will continue to thrive, entrepreneurs will continue to solve problems and you will be amazed by the career opportunities available to you. Study hard, learn about the sciences that interest you, push your self to learn math, visit the library and become acquainted with the writings of futurists.
