What does running a startup feel like?

Someone recently asked what it felt like to run a startup. It’s an interesting question, because you constantly get peppered with advice on how to choose your partners, what sins to avoid committing, and what events to go to but never get told how you’ll feel.

It’s not an easy subject to tackle with any brevity — emotions are, after all, complex — but I’ve given it my best shot.

First off, it’s very tough to sleep most nights of the week. Weekends don’t mean anything to you anymore. Closing a round of financing is not a relief. It means more people are depending on you to turn their investment into 20 times what they gave you.

It’s very difficult to “turn it off”. But at the same time, television, movies and vacations become so boring to you when your company’s future might be sitting in your inbox or in the results of a new A/B test you decide to run.

You feel guilty when you’re doing something you like doing outside of the company. Only through years of wrestling with this internal fight do you recognise how the word “balance” is an art that is just as important as any other skill set you could ever hope to have. You begin to see how valuable creativity is and that you must think differently not only to win, but to see the biggest opportunity. You recognise you get your best ideas when you’re not staring at a screen. You see immediate returns on healthy distractions.

You start to respect the duck: paddle like hell under the water and be smooth and calm on top where everyone can see you. You learn the hard way that if you lose your cool, you lose. You always ask yourself if you’re changing the world in a good way. Are people’s lives better for having known me?

When you have an idea it has no filter before it becomes a reality. This feeling is why you can’t do anything else.

You start to understand that the word “entrepreneur” is a personality. It’s difficult to talk to your friends that are not risking the same things you are because they are content with not pushing themselves or putting it all out there in the public with the likelihood of failure staring at you every day.

You start to turn a lot of your conversations with relatives into how they might exploit opportunities for profit. Those close to you will view your focus as something completely different because they don’t understand. You don’t blame them. They can’t understand if they haven’t done it themselves. It’s why you will gravitate towards other entrepreneurs. You will find reward in helping them too.

Your job is to create a vision, a culture, to get the right people on the bus and to inspire. When you look around at a team that believes in the vision as much as you do and trusts you will do the right thing all the time, it’s a feeling that can’t be explained.

The exponential productivity from great people will always amaze you. It’s why finding the right team is the most difficult thing you will do, but also the most important. This learning will affect your life significantly. You will not settle for things anymore because you will see what is possible when you hold out for the best and push to find people who are the best. You don’t have a problem anymore being honest with people about not cutting it.

You start to see that you’re a leader and you have to lead or you can’t be involved with it at all. You turn down acquisition offers because you need to run the show and you feel like your team is the best in the world and you can do anything with hard work. Quitting is not an option.

You have to be willing to sleep in your car and laugh about it. You have to be able to laugh at many things because when you think of the worse things in the world that could happen to your company, they will happen. Imagine working for something for two years and then have to throw it out completely because you see in one day that it’s wrong. You’ll realise that if your team is having fun and can always laugh at the fact that you won’t die. In fact, the opposite will happen: you will learn to love the journey and look forward to what you do every day even at the lowest times.

People will tell you not to get too low when things are bad and not to get too high when things are good and you’ll even give that advice. But you’ll never take it because being in the middle all the time isn’t exciting and an even keel is never worth missing out on something worth celebrating. You’ll become addicted to finding the hardest challenges because there’s a direct relationship between how difficult something is and the euphoria of a feeling when you do the impossible.

You realise that it was much more fun when you didn’t have money and that money might be the worst thing you could have as a personal goal. If you’re lucky enough to genuinely feel this way, it is a surreal feeling that is the closest thing to peace, because you realise it’s the challenges and the work that you love. Your currencies are freedom, autonomy, responsibility and recognition. Those happen to be the same currencies of the people you want around you.

You feel like a parent to your customers in that they will never realise how much you love them and it is they who validate that you are not crazy. You want to hug every one of them. They mean the world to you.

You learn the most about yourself — more than any other vocation — as an entrepreneur. You learn what you do when you get punched in the face many, many times. You learn what you do when no one is looking and when no one would find out. You learn that you are bad at many things, lucky if you’re good at a handful of things and the only thing you can ever be great at is being yourself which is why you can never compromise it. You learn how power and recognition can be addicting and see how it could corrupt so many.

You become incredibly grateful for the times that things were going as bad as they possibly could. Most people won’t get to see this in any other calling. When things are really bad, there are people who come running to help and don’t think twice about it.

You begin to realise that in life, the luckiest people in the world only get one shot at being a part of something great. Knowing this helps you make sense of your commitment.

That said though, it’s exciting. Every day is different and so exciting. Even when it’s bad it’s exciting. Knowing that your decisions will not only affect you, but many others, is a weight that I would rather have any day than the weight of not controlling my future.

That’s why I could not do anything else.
