Do you ever think to yourself that you can’t do this? That you’re not smart enough? That you haven’t practised enough? That you’re not ready? That you’re not good looking enough? That people won’t like you anyway? That you don’t know what to do? That people will think you’re weird? That you’re going to fail? That you’re going to disappoint someone? That you’re going to embarrass yourself? That you’re wasting everyone else’s time? That you’re not important enough? That he-said, she-said, and hence that means that he-thinks, she-thinks? That the conversations in your mind go round and round in circles?

We have all these conversations going on in our minds all the time. We don’t think we’re good enough, we think of how we screwed up last time, we think of all the decisions we make based on our past activities, we think of what other people think of us… But, do you ever stop and think: what am I actually thinking about? And is it actually helping me?

Because if it’s not helping you achieve what you want to achieve, then give it up. If saying to yourself that you can’t do something is not going to help you get something done, give it up. If you’re letting what other people may think about you affect your actions, then give it up. For in the infinite wisdom of Dr. Suess: Those who mind don’t matter, and those who matter don’t mind.

When the Fonz was younger and attending lots and lots of auditions, he would see lots of guys who were taller than him, more good-looking, and who seemed so much more accomplished. Instead of letting it affect him and his performance, he would say to himself, “I don’t have time for that thought,” and not think about it anymore. He usually got the part.

What are you thinking about? Is it worth your time?

Yeah, I know. I’m so cool, and I’m so lucky.

I have DNA, flesh, blood and bones.

Barack Obama and Steve Jobs are truly two icons of our time - men with great dreams, great visions and a commitment to getting stuff done.

We are all humans in the world; we have all had our own adversaries and our own stories, but we are all made of the same stuff, essentially. If Barack and Steve can do it, so can you. Seriously.

Have a goal. Plot the steps between now and the goal. Put dates on everything. Work your plan. That’s it.

When you learn something for the first time, everything is new to you.

So you explore, you try different things, you fall down, you fail, you fail, and you fail some more… But you keep persevering and you get up again and again and give it another go. There are no expectations and there are no critics, there’s only you and the work you are toiling away at. Then, people start to notice your work, comment and compliment you.

And suddenly, people begin to expect a certain style and excellence from your work in that field. You’re recognised and you can no longer be a fool - you’re an expert!

Now that you’ve learnt how to make it in that field, your once steep learning curve plateaus and your learning step increments shrink.

When this happens, find something new. Start something you can be arrogant about for not knowing, something where there is no expectation, where the only person whose curiosity you want to satiate is your own. Be playful, rejoice from and learn so that you grow. Branch out into something new and dare to create genius in what you know not.

Kieran O’Neill started up holylemon.com, a sight that shows funny videos, funny movies and funny videoclips when he was 14, and sold it for US$1.25 million while studying at the University of Bath, during his exam period. He was 19 at the time. Now 21, he’s working on PlayFire and PlayStation Universe, while finishing off his degree. He spoke at Imperial College recently, and dispensed the following advice:

(1) If you’re starting a technical company, have at least one technical co-founder. Have someone great.

(2) Raising capital from equity is the most expensive source of funding. It’s way better to bootstrap or borrow.

(3) Finding the right co-founders is essential to the business.

(4) Figure out what your key business metrics are, and measure obsessively.

(5) Get onto the feedback loop as soon as possible. I.e., launch as soon as possible.

Critics are those who stand on the sidelines waiting for you to muck up so they can laugh at you, point out your mistakes gleefully and then congratulate themselves on being clever enough to point out your mistakes to everyone else.

Even the most mediocre performer contributes more than the shrewdest critic.

If you want something to be great, don’t stand on the sidelines dispensing advice, (life experiences, overly generalised), get in there and make it great!

Be a performer, and not a critic.
