its so confusing understanding you its making me not want to do the things i know i should do

So, i went to Otago yesterday to have a look at the open day at the uni. And, i don't know how to explain it but i felt like something clicked, like yeah this is where i should be. I still don't know what course I want to do or the specific job i want to end up in but i really think that Otago is the place for me :) so that's really awesome, as i was starting to doubt whether going to uni next year was the right thing for me or not and this is just total affirmation that it is. I was thinking about what I'm passionate about to help me decide what job i would like to end up in and i came to the conclusion that the only thing i'm really passionate about is helping people. so i'm thinking social worker or something along those lines? i dont know what else there is... maybe do law and be a child advocate? je ne sais pas : /
