For the first two years of my undergrad I was in English. My mom passed away when I was younger and we had a really deep connection when it came to literature. English in high school was my favourite subject and it just made me feel like I was doing something that connected me to my mom. The only history course I took in high school was on Canada in the world wars... I enjoyed it but it didn't strike me as something I wanted to pursue. Looking back, I really enjoyed social studies, which was bascically bottom up history, but again it didn't jump out at me.
I took history as a minor in university and it blew my mind. I looked forward to every class and each midterm and assignment made me excited. It felt like the discipline just opened everything up to me - things clicked and my perspective changed on so many levels. English allowed me to study the human condition through art imitating life, but history magnified that approach. I contemplated finishing my English undergrad and applying to MA history programs, mostly because changing fields was daunting. I went to my first week of English classes at the beginning of my third year and hated every one - I had a history department booklet detailing all of its course offerings in my backpack and pined after them. Anyways at the end of that week I ate a pint of ice cream in my room while I switched my whole program online. The next week I was in all history courses and I haven't looked back since. I'm writing my honours in history right now (fourth year) and am waiting on hearing back on my MA in history applications
I think history is so important to study because it offers context to situations and proof that no matter how pernament something feels in society, things change. That seems obvious but when you're only young and have only known your situation to be the same, (whether it be living in a country that has a dictator or are an oppresed individual in a democractic country) history offers hope. History is so important for the present, and a very powerful tool that can be manipulated for both negative and positive outcomes. Because of this it is paramount that history is made accessible to the general public - knowledge is power and it can liberate.
And all of the many good reasons telkanuru pointed out!
