I absolutely love history, it's easily my favorite subject I've ever gone through in school. I think it all started when I was a kid, my dad would leave the history channel on and I'd just sit there and watch documentaries on old world war one and two planes and shit like that, got into highschool and my teachers made history such an enjoyable subject that I'd love to essentially follow in their footsteps, teaching students while making it an enjoyable subject to learn at the same time. I've had my share of teachers that have made me do packet after packet of work, and I know for a fact I learned way easier when the teacher was hands on, had us do group work, and had us really try to enjoy the class, whether that be through group work, or just being a funny guy
As far as astronomy goes, by far my favorite thing to research. I love to just watch documentaries on the universe late at night, some times I'll binge watch documentaries and videos and just learn. I just like to learn about it, it's pretty damn interesting, and I just enjoy the thought of one day being someone that contributed to finding life outside of our solar system (though that may not happen, it's not a far fetched idea, I'm sure by the time I'm out of the military they'll be closer to finding life, and hopefully I can contribute to that)
