Absolutely agree with this. I left on a round the world trip in April with my wife. We've been through Australia, South Korea, Japan, Taiwan, Hong Kong, Spain, Germany, Czech Republic, Hungary, and now Austria. I spend half of my time traveling / meeting people and the other half building my mobile app business. The trip is costing us about $5000/mo (using airbnb and being fairly liberal with spending on food and attractions, we have 0 expenses in the states since we packed everything into storage), but I've managed to triple revenues this year to ~ 25K/mo, so if we wanted to we could do this indefinitely.

I know many people who are working 80 hrs/week on their startup while letting life pass them by (including a few in YC), but I wouldn't trade places with them. These days it is entirely possible to build a company and live your dreams at the same time.
