"Luckily, I was able to get a job in a primary school in 1983 and I stayed there until I retired six years ago."
However, juggling a full-time job as a teacher with the farm was a challenge at times.
Henry bought cattle at about one year, bringing them on until they were ready to be sold, which allowed him to keep labour to a minimum.
"I got up in the morning before I went to school and did whatever had to be done, which was mainly the feeding," continued Henry, who is a father of seven.
"Then I went to school and because it was a local school I could be home for about 3.30pm and get on with things on the farm."
But, in keeping with the same passion he has displayed throughout his farming career, it wasn't long before he began to look at ways to increase the income from the 30 acres he owned.
"When you have something about 20 acres it is more of a hobby really," he said.
"There isn't enough throughput to generate a wage and at the end of the day that's what every person is looking for.
"We all need a certain amount of money at the end of the week to pay the bills."
The farm was ticking along but disaster struck in 1996 with the BSE outbreak and the European Commission imposing a worldwide ban on all British beef exports.
"We had a really bad year that year and we decided to do something different.
The change for the business came in the form of Limousin cattle and Henry began a breeding programme that has seen his farm turn out some of the most sought after cattle in the world.
His first taste of success came in 2009 when he sold one of his pedigree Limousin heifers for 38,000 guineas.
"That was eight and half years ago and it was unbelievable," he said.
"It gave us a great feeling of success."
Keen to build on this, Henry turned to advances in science to develop the business even further.
He now uses a technique known as flushing, which allows him to produce more Limousin cattle, increasing the income for the farm.
"Basically when you have a really good animal you want it to produce as many calves as possible but each cow only produces one egg, so we use a technique known as flushing which encourages them to produce maybe as many as 10 or 15 eggs.
"These are then fertilised inside the cow before they are implanted in the surrogate.
"Alternatively, the embryos can be frozen so you have them there when you want to use them.
"This technique really has taken us to the next level.
"Of course, it isn't without its risks, it is extremely expensive and sometimes it works and sometimes it doesn't.
"However, we're always looking to improve things.
"Four of my sons are interested in farming and they come in the evening, holidays, weekends to help.
"Ultimately the farm will be passed on to my children and I am constantly looking at ways to develop it.
"Breeding the Limousins has become very important, more than half of our business now is producing these quality animals and flushing has allowed us to build develop a lot quicker than we would have otherwise."
The pinnacle of this, of course, was the sale of the infamous Jagger who ended up as reserve overall champion at the Show before his subsequent world record sale at Carlisle. oral
Like many farmers, Henry lays great store by showing his prized animals at events like the Balmoral Show as a way of making the all-important sales.
He is a regular face at the Balmoral Show where he meets potential buyers and builds relationships with other people in the industry.
"Some of these people spend half an hour talking to you and might come back and buy something off you six months later," said Henry.

"You have to look after the customer and do good by them and the chances are they will keep doing business with you."
Of course, the business side of farming is not necessarily for everyone, but it is something that Henry enjoys.
"It's such an important part of farming," he continued.
"At the end of the day, that's why we do it, we have to make money at it.
"Some people say Balmoral is a waste of time but I don't look at it like that, I look at it as an opportunity to build and grow the business."
In fact, Henry is looking forward to taking offspring from a cross between the lucrative Jagger and prized heifer Trueman Euphonium to the Balmoral Show in just over two weeks.
And despite the eye-watering sum fetched by Jagger, Henry is not content just to rest on his laurels.
"We're always looking at ways we can develop," he said.
"If you're not trying to improve then there really is no point.
"The idea is that we're constantly trying to produce something better in the next generation.
"You want to be able to look back 10 years and see the improvements in the breed and that's something we are totally committed to achieving."
