The life hacks are for you, not to be better for your partner. Yet...
If your partner loves you, she gains in a few ways from your improvements.
1) She gets a better you. You are a more attractive person to her, because you have more going on in the positive dimension.
2) If she cares about you, she wants you to thrive. She should be happy for you.
3) You are setting a good example. You are a close-up model of what it's like to be living a good life.
Of course, if your partner is already doing the right things, then she will be a model for you as well.
