tips on to have a successful married life?

I have been married for 25 years this month and I would have to say that the best thing I can tell you is to be honest and share the work load. Don't waste money without agreeing between you and you will have a long healthy marriage. When it all becomes one sided the end is on the way. It may not end in divorce or splitting but it will split you internally and that takes most of the happiness out of marriage because it's always in the back of your mind.
