What’s more, this wasn’t something we did in the office – there was no “Bootstrap team” – no 20% time – just Mark and I hacking in our free time. And this is significant, because what building Bootstrap has taught me more than anything else, is that’s all I really care about.
There’s nothing more rewarding than working on something you love, and something you care about, particularly if the person(s) you’re working with share that enthusiasm.
