The second most important decision you can make in your life is who you will marry. That decision will affect your daily happiness for the rest of your life. 

But after you make that very important decision, the real work begins. Marriage is hard work. It is very hard work, but it is also very, very rewarding. You have to work at marriage to make it successful. You want your children and your grandchildren to have happy marriages that last and bring more joy than difficulty. 

Pass on the things that worked for you such as;

Use as many nicknames as possible

Never go to bed angry

Go to bed at the same time

Money is very important. Talk about it.

Learn their love language

Make your marriage your highest priority

Marriage is a union of two successful forgivers

Prioritize sex

Go on dates

Be your spouses biggest fan

Pray together

Have talks 

Be quick to forgive

Let the little things go

Honesty

Trust

When something is bothering you, talk about it

Family meals

Make time for the two of you

Flirt with each other

Laugh with each other

Go for walks on the beach and hold hands

Watch sunsets together

Also pass on the things that don’t work.

Stonewalling

Not forgiving

Infidelity

Trouble with finances

Not being prepared for marriage
