I wouldn't prioritize, "making her life as easy as possible," but rather teaching her discipline and how to overcome challenges and obstacles when she is older so she can make her own life as easy as possible. Kids who have it too easy growing up have it bite them in the ass when they're adults and the smallest problem sends them into a spiral of anxiety and depression.
However, the best thing to do is to be there. Make sure to teach her what is right, and wrong. Teach her how boys can be like, so she can keep herself safe. She's gonna look to you for the rest of her life as a foundation of security, so always let her know that no matter how upset you are with her, or whatever happens, you got her back.
