What is the secret behind your success? originally appeared on Quora: the place to gain and share knowledge, empowering people to learn from others and better understand the world.

Answer by Vlada Bortnik, CEO and Co-founder of Marco Polo, on Quora:

I'll start by saying that success is in the eye of the beholder. For one person, it could mean running a profitable company, for another it might be writing a novel or planting an organic garden. Success is personal, subjective, and completely your own.

For me, success relates to both my purpose and my journey. When my husband, Michal, and I decided to start a company together, we began with something that was meaningful to us - wanting to make the world a better place by creating a new technology that had the potential to bring more happiness to at least one billion people on the planet. (We're both immigrants, so the only way we know how to work is hard. And we decided that if we were going to work hard, we might as well shoot for making a big impact!) Personally meaningful and high-impact work became even more important as we started a family because that's what we wanted to model for our kids.

We began researching happiness and learned that having meaningful connections is one of the key ingredients to feeling happy. At the same time, we were experiencing our own challenges in staying connected with our far-flung families. Ideas began to percolate, and before we even knew what it was that we were going to work on, we knew its purpose would be to help people feel close. We built our company from this simple but very meaningful premise, and now Marco Polo is helping millions of people rediscover the blessings of authentic relationships every day.

So from that standpoint - looking at what we've created and how we're making a difference in people's lives - I feel successful. But I also believe that success isn't just about achieving an end goal. It's about being fully present during all those days in between, and feeling the joy in that journey.

I recently read The Score Takes Care of Itself: My Philosophy of Leadership, by Bill Walsh, who is considered one of the greatest coaches and leaders in NFL history. The quote that inspired the title has really resonated with me: "There is no guarantee, no ultimate formula for success. It all comes down to intelligently and relentlessly seeking solutions that will increase your chance of prevailing. When you do that, the score will take care of itself."

As I keep my eye on the purpose of Marco Polo, I also invest 100 percent in enjoying the journey. I'm able to do that because I'm passionate about what I'm doing, the talented people around me are also invested in our purpose, and we invest in the process. So when we look back on this time in our lives, we'll be able to feel good about what we've done and how we've done it, regardless of the outcome.
