What is the best support an ordinary family can give their daughter?

It is spending money on braces for her during adolescence and helping her lose weight.
It is using both gentle and firm methods when she doesn't want to go to school, pushing her to finish her undergraduate degree.
It is using all available connections and resources after she graduates to help her find a stable, respectable job that can support herself.
It is doing your best to buy her a house and a car in the city where she works, or if you can't afford that, at least chipping in to rent her a decent apartment with a private bathroom.
It is not giving an inch on the bride price she's entitled to at marriage, while also preparing an equal or even larger dowry, all under her personal control.
It is telling her she can always come back when her marriage is no longer working, and finding the most reliable lawyer to help draft a statement supporting child custody.
It is purchasing health insurance early, exercising regularly, taking care of your own health, and trying not to add to her burdens.
If you can't do any of these, then do the simplest thing: shut up. Don’t pressure her into marriage, don’t rush her to have children, and don’t hijack her life with the phrase "It's for your own good."
