The only real security that a man can have in this world is a reserve of knowledge, experience and ability. 

There is joy in work. There is no happiness except in the realization that we have accomplished something. 

I believe God is managing affairs and that He doesn't need any advice from me. With God in charge, I believe everything will work out for the best in the end. So what is there to worry about. 

Once an organization loses its spirit of pioneering and rests on its early work, its progress stops. 

All the problems of the world could be settled easily if men were only willing to think. The trouble is that men very often resort to all sorts of devices in order not to think, because thinking is such hard work. 

If you want to achieve excellence, you can get there today. As of this second, quit doing less-than-excellent work. 

In war as in life, it is often necessary when some cherished scheme has failed, to take up the best alternative open, and if so, it is folly not to work for it with all your might. 

I don't think I've ever worked so hard on something, but working on Macintosh was the neatest experience of my life. Almost everyone who worked on it will say that. None of us wanted to release it at the end. It was as though we knew that once it was out of our hands, it wouldn't be ours anymore.

Most people have no concept of how an automatic transmission works, yet they know how to drive a car. You don't have to study physics to understand the laws of motion to drive a car. You don't have to understand any of this stuff to use Macintosh.

The people who are doing the work are the moving force behind the Macintosh. My job is to create a space for them, to clear out the rest of the organization and keep it at bay.

Part of what made the Macintosh great was that the people working on it were musicians, poets, and artists, and zoologists, and historians. They also happened to be the best computer scientists in the world. But if it hadn't been computer science, these people would have been doing amazing things in other fields.

Design is a funny word. Some people think design means how it looks. But of course, if you dig deeper, it's really how it works.

It's not the tools that you have faith in - tools are just tools. They work, or they don't work. It's people you have faith in or not. Yeah, sure, I'm still optimistic I mean, I get pessimistic sometimes but not for long.

That's been one of my mantras - focus and simplicity. Simple can be harder than complex: You have to work hard to get your thinking clean to make it simple. But it's worth it in the end because once you get there, you can move mountains.

Design is not just what it looks like and feels like. Design is how it works.

Your work is going to fill a large part of your life, and the only way to be truly satisfied is to do what you believe is great work. And the only way to do great work is to love what you do. If you haven't found it yet, keep looking. Don't settle. As with all matters of the heart, you'll know when you find it.

There is tension all over the country. The party in Bengal has done substantial work. They have eliminated a few officers. The Englishmen are terrified. As a result, they have started sending their families to Britain. After some time, they will realise that they cannot exercise authority over India.

Faith is not avail in absence of strength. Faith and strength, both are essential to accomplish any great work.

Work is undoubtedly worship but laughter is life. Anyone who takes life too seriously must prepare himself for a miserable existence. Anyone who greets joy and sorrows with equal facility can really get the best of life.

Our consistent effort towards the development of a nation can make the whole country proud all over the world, but the lack of teamwork can surely make us familiar with huge disasters.

It can be simplified easily, if an individual works his heel peak for the freedom of the nation, he might get punished by the Englishmen, but if a group of individuals form a community to fight for freedom, they get success. 

The ambition of the greatest men of our generation has been to wipe every tear from every eye. That may be beyond us, but so long as there are tears and suffering, so long our work will not be over.

An economically peaceful and prosperous Sri Lanka is the dream of youth of the nation. My message for the youth is to collectively work for an inclusive developed Sri Lanka.

It's when children are 15, 16 or 17 that they decide whether they want to be a doctor, an engineer, a politician or go to the Mars or moon. That is the time they start having a dream, and that's the time you can work on them. You can help them shape their dreams.

You see, God helps only people who work hard. That principle is very clear.

My message, especially to young people is to have courage to think differently, courage to invent, to travel the unexplored path, courage to discover the impossible and to conquer the problems and succeed. These are great qualities that they must work towards. This is my message to the young people.

Let me define a leader. He must have vision and passion and not be afraid of any problem. Instead, he should know how to defeat it. Most importantly, he must work with integrity.

If four things are followed - having a great aim, acquire knowledge, hard work, and perseverance - then anything can be achieved.

Never stop fighting until you arrive at your destined place - that is, the unique you. Have an aim in life, continuously acquire knowledge, work hard, and have perseverance to realise the great life.

Look at the sky. We are not alone. The whole universe is friendly to us and conspires only to give the best to those who dream and work.
