Throughout the semester your students have been learning how to be successful at college. Part of that involves doing some personal exploration about themselves; to learn about their own personality, values, and goals.
The first step for your students is for them to do a personal evaluation. 
This self-knowledge will help shape their career choice. Below are some assessment tools to help them along this process.
Like any journey you may go on, it is useful have a road map. College is a time of discovery and exploration. It is helpful to students to find a field of study and create a map that will help guide them to a fulfilling career and life.
According to CareerFocus:

One reason to look at education and training after high school is because education can influence your full-time employability and salary. The U.S. Department of Labor shares this data from 2019.
"You've got to find what you love. . . Your work is going to fill a large part of your life, and the only way to be truly satisfied is to do what you believe is great work. And the only way to do great work is to love what you do."
