I find some similarities between managing money and managing relationship.

- You need to pay attention.
You pay attention to people you like and cultivate relationship. You pay attention to money and money will grow.

- You invest your time.
Developing good relationship takes time, and accumulating financial stability also takes time.

- Sometimes you need to keep distance.
If you're always together and too close, relationship may suffer. You also give some distance with your money and give it some room to grow.

- There will be some ups and downs.
Like marriage, we experience ups and downs in our savings and investment.

- If you treat the person nicely, you will be treated well in return.
If you treat money with care, it will reward you with a nice return.

In general, people who are managing their relationship well seem to be financially stable, too. It's just my observation.
