Like everyone said, 21 is freaking young. I wasn't even finished with my bachelor's degree. And at 24 I moved halfway across the world, meeting people from every background and broadened my perspective. At 21, one's whole life is literally still coming up. Don't waste that on having kids.

23 here, I moved halfway across the world, met people from every background and I am still broadening my perspective… with a baby lol, and am a business owner that is still putting in work towards other skills. 
Saying this to remind people it is fully possible for people to do both if you want!
