I kinda thought I'd be more elated that i passed my degree but maybe I'm just being cynical and that's why i want to make sure i get the role I truly are passionate about straight away....
Passions change over life.
For reading material, I strongly suggest the book "What Color Is Your Parachute?" which has been updated every year for many decades. Pick up any recent edition, you can find them in a library or used book store if you'd rather not buy them.
Somewhere in the book (it varies by edition) is an exercise called the "Flower Diagram". It is meant to be an introspective exercise where you evaluate your most passionate skills, your most passionate work environments, your most passionate people-groups, and other areas of life where you have passion. Doing the exercise well typically reveals that a person has unexpected areas of passion, sometimes broader than expected, sometimes pointing in a different area than expected.
I personally like to do the flower diagram about every five years, and compare it to what I had in the past. I discover my passions drift. While some have remained constant, such as my love of software, love of creative fields, others have drifted between different groups, different responsibilities, different geographies.
Consider working through it and learning more about your own passions.
