It took three of us nine months to go from napkin to reality. We were close, efficient, and most importantly, cheap. We epitomized what it means to be bootstrapped and were damn proud of it. We broke all the rules. We didn’t raise money, worked short days, and even did client work on the side. And yet just three weeks after launching, Flow was turning a profit. One year later, we’re bringing in over $500,000 in recurring revenue and growing like crazy.

We should respect the way our mind works and work in a similar fashion. From a UX perspective, we can design software, websites and all digital interfaces to minimise distraction and focus the user's attention onto one task at a time. This means you can't have all the tools in the toolbox in front of you when you work. We can give our users more of a holding hand as they are guided through a clear workflow that helps them accomplish one task, and THEN another... and another. One at a time, considering what communication and information is really worthy of interrupting your precious concentration and when you should seek out new data.via methodsandtools.com
