Here at Sakonnet DesignWorks we are always working on something new. Talk about the feeling of butterfly's, then doubting yourself and your capabilities.

Doubt usually comes from shaking things up so we are always pushing forward and honing our skills to help our clients navigate the product development process.
Very good article addressing this topic, enjoy!
