A couple have shared their top tips for a happy marriage - 17 years after being told not to wed.
Lisa and Tom Bilyeu instantly fell for one another after meeting almost two decades ago - and have gone on to share the secrets to a successful marriage.
In a post revealing their best advice for other couples, they named having sex often as their number one tip.
This was followed by 'communicating obsessively', and being honest with one another - 'especially when it's hard'.
The couple, who co-founded billion dollar health brand Quest Nutrition, also said forgiving mistakes fast and always wanting the other person to win were keys to happiness.
They also said making marriage your highest priority will help maintain a strong bond.
Revealing details of lessons learnt over the past 17 years, Lisa said on Instagram:"When you love someone so damn much all you want to do is see them happy.
"Seeing Tom smile and laugh is literally one of my most favorite things on earth.
"And so knowing that what you are about to say is going to do the exact opposite? Well my instincts are always to just keep it to myself. But in not saying it, for Tom and I, is as bad as lying."
"We plan to be married forever and so it needs to be built on 100 per cent honesty and transparency.
"And so when I'm 90 years old and a bag of wrinkles, and I wake up with no make up on and he looks at me and tells me I'm beautiful, he needs those moments to carry weight."
However, in contrast to their best pieces of advice, Lisa always revealed the worst advice she ever received - saying 'don't marry Tom' was number one.
She also said being told to have kids or risk living an unfulfilled life was one of the worst pieces of advise she had received.
In response to his wife's gushing post, Tom replied: "My marriage to Lisa is my highest priority.
"Why? Because nothing has given me more joy, ever. All the money in the world can't come close to having someone who lifts you up and pushes you to be better.
"My wife is my all-time favorite human."
