So glad to hear of your interest in joining the hospitality industry! The industry is rather broad - are you most interested in hotel management or food/restaurant management? Both are very interesting and exciting fields in which hospitality plays a major role.
I am sure you are applying to college programs that have hospitality and food service management areas of study. Get in touch with your academic advisor for guidance, but also look to professors and older classmates - they will be invaluable resources to you.
Whether you are interested in hotels or restaurants, I would recommend looking into part time work while you are in school and potential internship opportunities during summer months. Taking a part time job will help you understand the business from many angles. It will help you when you decide to take the step into management as you will be able to better empathize with your employees - and empathy is a major component in hospitality!
Hope this helps!
