People who are serial entrepreneurs or just people who like building things, get good at building things (quickly).

We learn to use the right tools for the job, we use new light weight technologies and we build our own frameworks and scaffolding to allow us to build things quickly.

We make the mistakes that take up all our time on previous projects and avoid them on the new ones we do.

We have a plan of action right from the start and know what we're going to be doing each step of the way.

The first time you learn something, whether it's programming, building something for the web or even just trying to use a certain API - it will take a lot more time than the future iterations. However, it's this process that will allow you to get more efficient in the long run.

A weekend truly dedicated to building something in one sprint can be far more productive than weeks or months of trying to fit in occasional hours of work in our spare time. Don't forget also, that a dedicated weekend (inc Friday evening) could be a total of 54 hours (if you don't sleep), as a comparison a bootstrapped project may only have a few hours a week available - therefore the same objective will take months to complete.
