Attend enough business conferences, read loads of LinkedIn posts, or listen to enough motivational speakers and you’ll hear one piece of advice repeated over and over again: You’ve got to love what you do! If you don’t love what you do, you might as well stay home. No less a giant than Steve Jobs famously told Stanford’s 2005 graduating class, “The only way to do great work is to love what you do. If you haven’t found it yet, keep looking. Don’t settle.”

There’s nothing wrong with loving what you do, of course – I just don’t think it’s a prerequisite for starting a business or building a fulfilling career, let alone doing great work. In fact, I think it’s disingenuous for really successful people to put so much of the focus on love, just as it’s disingenuous for really rich people to say money doesn’t matter. People tend to romanticize their own motivations and histories. They value what matters to them now, and forget what really mattered to them when they started. It’s human nature, so it’s an easy thing to do.

Many great businesses and important innovations are actually born out of frustration or even hate rather than love. I talk to entrepreneurs all the time, and many of their companies sprang into existence for similar reasons—because the founder wanted something that didn’t exist or scoped out an opportunity to do something better than it had been done before. Love for their subject matter may or may not play a role in their stories, but hate for the existing options, along with strong opinions about how things could work, does and is a much better predictor of success.

My own career is no exception. Back in the mid-’90s, I was looking for a simple tool to keep track of my music collection, and all of the available programs seemed bloated and unnecessarily complex. Those are two things I despise, so I set out to make my own tool and eventually released it under the name Audiofile. I didn’t love music collecting. I didn’t even love software development. (I was just learning it at the time.) And I didn’t have any aspirations to run a software business – I just saw a need, couldn't find anything I thought was great, and I built something better. Nothing wrong with that. A similar situation led me to start 37signals and build Basecamp and HEY.

Even today I don’t always love what I do. The paperwork, the reporting, the day-to-day minutiae that come along with responsibility for growing company that's bigger than it's ever been – none of those things make me swoon. Yet I’d still rather be running 37signals than doing anything else. I think I’m fairly good at it, every day I get to do challenging, creative work, and I continue to find making better software a worthy and rewarding cause. It’s also a real pleasure to work with such amazing people as I do every day of the week. Isn't that plenty?

If I were giving a motivational speech, I’d say that, if you want to be successful and make a real contribution to the world, you have to be intrinsically motivated by the work you do, and you have to feel good about spending your days on it. Love might grow – and it’s a wonderful thing if it does—but you don’t need it up front. You can succeed just by wanting something to exist that doesn’t already.
