Many young people are overwhelmed by the amount of the things that they want to do, and need to do, while their time is by no means unlimited. How to govern their studying satisfactorily and stay capable of enjoying the happiness of the present moment? This presentation outlines an investigation into the impacts of a toolkit provided through ‘Understand yourself to love yourself’, a lesson in the course of Emotional Intelligence and Social Development (EISD), on 50 students at ULIS – VNU. Data of this mixed-methods research included participants’ daily and weekly journal reflections, self-care and self-satisfaction tests. Our findings revealed the impacts of developing emotional intelligence on the students’ autonomy. We further suggest the toolkit as a method to help students improve their self-management- to improve themselves each day while treasuring and loving their present selves, so that they can strive for their future with all of themselves and simultaneously enjoy their happy youth moments.
