A quote by Dick Costolo that rings very true and close to home. One of the great reasons for being part of a start-up.
"In the beginning, you are the most limited in terms of resources but the least limited in terms of range of motion. It's easier to innovate and change directions in the early days, but it's harder to do nine things at once. This is probably the founding team's favorite part of the lifecycle of the company. Everything is possible, and you can really focus on building the most awesome product/service possible"
