A day in the life of a teacher in the US? 😮

Je
If you are a teacher I'd love to hear what it's like. (Sorry, I know it's weird asking this on a <a href="https://play.google.com/store/apps/details?id=com.glow.android.nurture">pregnancy app</a> haha but I figured it's worth a shot.) What are the best parts of your job, and what are the hardships that outsiders may not see? 
I am considering becoming a certified elementary school teacher in NJ soon, but I majored in something other than Education in undergrad so I'd have to take an alternative route through a certification program. Is it hard to get hired if you do not have a bachelor's in Elementary Education? 
Thanks in advance! 💕
