At the core of ever­evolving technology industry, there are a few key individuals who have left a deeper mark and changed the lives of many, giving them motivation and the will to persevere to the end.

·Sunder Pichai—the current CEO of Google

Sunder Pichai was not born with a silver spoon in his mouth. However, his story never fails to remind all that with determination and hard work, one can beat the odds. During his time as CEO, Pichai led the launch of Google Chrome, Google Drive and Google Maps, which are features that have revolutionized modern lifestyle.

·Steve Jobs—the late CEO of Apple

The life of Steve Jobs can be compared to that of a rollercoaster. He was fired from the company that he co­founded (known as Apple now), then he went on to start up two other successful companies, before returning to Apple, where he created the iPhone, a most significant invention of this century.

·Elon Musk—the founder of SpaceX and Tesla

Elon Musk used to be a major shareholder in PayPal and was also its CEO but was dismissed due to disagreements with the company leaders. He left PayPal and went on to establish SpaceX and Tesla, both of which turned out to be successful companies. Currently, he has set his sights on ways to reduce global warming, including keeping a lookout for new sources of renewable energy, and has an exciting ambition to establish a human colony in Mars.

·Sal Khan—the pioneer of online education provider

He may not be as famous, but his contribution to education deserves as much credit. Using his website, anyone can have unlimited access to educational videos that teach just about anything for free without attending a formal course. In fact, it was not an easy process. There were a lot of dying moments when he was stressed out, but anyway he made it.
