It’s definitely vital to have safeties, there’s no denying that. You don’t wanna end up in a bad position. That said, you only apply to college once! Have fun with it. If a particular school seems really cool or amazing, apply! Don’t let finances or acceptance rates deter you from the mere act of applying; as long as you’ve got your safeties locked, there’s no harm. The worst thing that can happen is that you don’t get in/can’t afford it. Or, you might get in and get lucky with a scholarship 
So just make sure you have the full range – you can be practical and dream big all at once.
