In our discussions at Proton, we keep implying that your ambitions should be very big, and some of you ask, "What if we never meet those goals? Won't we be disheartened?"
The answer is simple, "If the goals are about YOU, then of course you'll feel broken. But if the goals are about something larger than you, then you'll be all right."
For me, this realization came while I was at Stanford. I had just finished my IIT at the top of my class, been funded by a prestigious fellowship for Stanford, my Master's was going okay, I had many options in front of me - and I felt confused and low. Which road should I pick, I asked myself. Should I be a consultant at McKinsey? A corporate executive? An academic at some good university? An entrepreneur? Should I come back to India? Or should I do what all my colleagues were then doing and stay in the US for a while? What if I make the wrong choice - how dreadful will that be!
Then I remembered what Gandhiji had said, and I quote from memory, "When in doubt as to what to do, remember the face of the poorest, most wretched person you have seen. Do what is best for that person."

I was walking when I remembered this, and I literally stopped in my tracks. Imagine the sprawling Stanford campus, tree covered roads, bicycle paths, low yellow buildings with red roofs, a Californian idyll. And me standing there, marveling at how my life had suddenly become clear.
I am not as great a person as Gandhiji was, so I immediately adapted his rule. My personal rule became - and I remember it to this day - "Primarily, try to create the most happiness for the most people over the course of your life. Secondarily, give yourself a chance to achieve the things that excite you." I've never felt confused again about the direction I want to take. I started working with Manu with just this rule in mind.
The same thing will occur to you within a company. Someone will backstab you, someone will steal credit for what you have done, someone will speak harshly to you. Think beyond yourself. Think about the good of the company, work for the good of the company, see if you might be misunderstanding the situation, keep moving forward. Do not get bogged down by petty things. It's natural to be hurt by what others think and say - it happens to everyone - but try to control your thoughts, set your ego aside and think about the greater good. Think beyond yourself.
Warning: The one place where this doesn't work well is in matters of the heart! In relationships with family and friends and significant others, it is much more difficult to think beyond yourself. That is why these relationships are very special, perhaps the most valuable and vexing things of all!
