Twitter cofounder Biz Stone shares the most important lesson he learned in his startup career

If I had to say one thing, the most important thing, and I did it wrong enough to realize that now I know what it is. Success is not guaranteed, but failure pretty much is guaranteed if you're not emotionally invested in what you're working on. We didn't care about podcasting. That's why Odeo didn't work. It's not because Apple got into podcasting. We could have pivoted and done something else. We didn't podcast and we didn't listen to podcasts. But with Twitter, early on, Evan had a tweet that said, sipping Pinot Noir after a massage in Napa Valley. And it made me laugh out loud. I had kind of an out of body experience because I was like, I'm laughing out loud at something I'm working on. And then once I realized that, I was like, I love what I'm working on. And that carried me through unbelievable amounts of negativity for the first three years of Twitter. Everyone saying, how stupid. If I wasn't emotionally invested in loving it, I would have believed everyone. So that's the one thing that I always say. You might have an idea that you think other people will like this. I think that's the wrong way to go scratching yourself. You have to love what you want to do. Yeah. That is what my one piece of advice is. Have emotional investment in your work and you will be far more likely to succeed.
