Originally I went in with a double major in sociology and communications because I felt like I needed to major in at least one "sensible" major so I chose communications. But I took philosophy as my sequence and I fell in love with it. My then lecturer invited students to this philosophy symposium and he saw my interest in philosophy (I had never dared even think about why I kept choosing philosophy modules during my degree) so he said I could speak to philosophers there and ask them about their work so that I could also see what the field was like.
I almost didn't go but I went and I knew that philosophy wasn't a passing fascination for me. I didn't want to go because I was scared of having to tell my parents that I wanted my double major to be philosophy and sociology i.e. two interests that people told me were not a sensible career path. But I loved it and I realised that I could actually just go to the offices and change my majors and no one could stop me so I did. People were dubious of my decision but I ended up tutoring second years in modern philosophy, African philosophy and the ethics of AI, and now I am doing my masters, so I would say that it is a moment where I exercised my free will that worked out. It isn't my favourite because it worked out though.
It is my favourite because I was willing to risk it not working out. I exercised my free will fully knowing that it might "go wrong" and I did it anyways because I decided that the chance of it going right was worth it and I trusted myself to live with whatever the outcome would be. I still feel the electric sensation of being assertive in a decision that I made on the basis that I wanted to do something because it would make me happy, not because I was concerned with the shame of not meeting people's expectations.
Funnily enough I actually loved communications and I still keep up with research in it, its just that my favourite parts about communications are also not the "this will get you a job" sensible aspects of it, those parts were just okay to me. This decision had a domino effect on how I live my life, it got me back into making art, it made me interested in film, made me realise that I love teaching, and perhaps most importantly it made me brave. There is a version of me somewhere that is too timid and afraid to really live but instead, because of that one moment where I said "fuck it" and just did what I wanted to do without overthinking it, I am passionately and intensely alive. And prone to getting my hopes up lol.
