Tim Cook, the boss of Apple, last night captivated a Glasgow audience during a lightning visit to the city.
The chief executive of the world's most valuable company passed on his wisdom, spoke of his values and gave his views on the US immigration policy that he said had gone against Apple's beliefs of treating people "with dignity and respect".
Cook, 56 - CEO since 2011 of one of the top 10 biggest corporations in the world - was speaking at the University of Glasgow after receiving an honorary doctorate of science.
He told a 1,000-strong audience of students and staff: "My advice to all of you is don't work for money - it will wear out fast, or you'll never make enough and you'll never be happy, one or the other.
"You have to find the intersection of doing something you're passionate about - and at the same time something that is in the service of other people.
"And I would argue that if you don't find that intersection, you're not going to be very happy in life.
"I've been very fortunate to wind up at an incredible company where I am very passionate about what we do, and it also stands at the exact intersection of my values."
Earlier, Cook said it was a huge honour to be in the city and being recognised for his work.
He said: "This is quite a privilege to have a degree with all of you from one of the finest universities in the world, and I am truly humbled by it.
"We're all very fortunate to be alumni - and I count that to be one of life's blessings.
"I would particularly like to say thank you to Murdoch MacLennan [the Chancellor’s Assessor, senior UK media executive and former CEO of the Telegraph Media Group] - a long time friend of mine who introduced me to the university and who has given me incredible advice for many years on many different subjects."
But his main theme was the values that push him and his corporation in what they do.
"The main thing that Apple will always do is provide products to others that empower them to do great things," he said.
"We will touch more people doing that than anything else we do.
"But we also advocate for human rights around the world, and so we have a very simple philosophy that everyone should
be treated with dignity and with respect.
"It sounds so simple but there are so many cases literally in every country of the world where that doesn't happen today."
He went on: "And we also care very much about our planet - and our concept or our philosophy is we want to leave the world better than we found it.
"And so we set out on an aggressive goal - what seemed aggressive at the time - to run Apple on 100 per cent renewable energy.
"If you look at many of the company's that have aggressive goals it's maybe 20 per cent by 2030 or something like that.
"We wanted to do it quickly - and I am very proud to tell you that today we run Apple on 93 per cent renewable energy.
"And we're going to make that extra seven [per cent]. So this is very important for us.
"We've now expanded that to work on our whole supply chain - and we're driving the supply chain to 100 per cent renewable energy."
He added: "We also focus on education because we see that the top problem in the world between the haves and have nots, generally, the root cause is education.
'If you put it very simply, people don't have equal opportunity.
"Too many times equal opportunity depends on being born in the right place.
"And this has never seemed right to us - things start off in a way that's not equal for people.
"We focus on serving under privileged and under-served kids in schools…"
Cook said: "We will not fix everything obviously, but we want to do our part and do as much as we can."
He also said Apple was working with rock star Bono on Product Red - a project to end the transmission of Aids/HIV between mother and child.
"Not reduce it but eliminate it," he said. "And we believe we can do that by 2020, which is not that far away.
"If someone had told you that a few years ago I don't think anyone would have believed it, and yet we are really that close."
Concluding, he added: "You can sort of put all those things (values) together and in a simple way say: we're an empowerment business.
"We try to empower people - it's in the way we design our products. We design our products so that blind people can use our products.
"We have incredible design teams that really think through every disability that people can have - so that the iPhone or iPad or Mac is accessible for them.
"Because we know that if our technology is not accessible to them, then it can't be life-changing."
On the US immigration ban, he said the policy had caused a "crisis" for employees in his company but he was “optimistic" that the courts would overturn the US government’s executive order.
He said: “Our simple view is that Apple would not exist without immigration. So this is a huge issue for us.
“So, what do we do? We voice our opinion and we stand up and we don’t sit in silence.”
