这个怎么翻译“我要努力，因为我要给她幸福”

I'll cheer up in order to bless her.
cheer up,努力，振作，开心起来，可以兼容逆境与顺境的语境。因为没有上下文，这里的努力不知道是努力学习、努力工作还是努力生活，也不知道是鼓励自己还是勉励自己，所以用cheer up比较宽松。
bless sb. 这里不是保佑，而是令某人幸福，使某人快乐，保护某人。语义比较广也比较灵活。

I should make great efforts, because I want to give her happiness

I need to work hard since I want to bring her happines.

I want it hard, because I want to give to her happily
希望可以帮助你

i will work hard to give a wonderful future

I shall work hard, because I want to make her happy.
