I think babysitting a baby overnight can be a good insight into if you will want children someday.ย
And don't fall hard for those high school guys. I get sometimes it works out but it never did for me.
Hang out with friends and enjoy being young and free by engaging in activities with them. When I was a teen I played in the river in my hometown. We played hide and seek covering a whole block of the neighborhood.ย
Start working on what job you would like, or if you want to go to college think of what you would major in. Keep your options loose until you're older though, this is just to give you a general idea of where you would like to go. And when you're older keep a second choice (a back up plan) because one day you will learn that being an adult is a lotta oops that didn't work out.
