I'm working on staying in this mindset. I know in theory how valuable my skills, experience and network are. But putting an actual monetary value to it, well, it's not how I'm used to thinking about my personal value. I've lead a career of "salaries" and "hourly wages". This is a totally new way of thinking. Add to this a lifelong fear of being seen as "conceited" or "full of myself" and you've got my general discomfort negotiating terms that reflect my worth. But, I'm still learning. Now I start with what I think I should charge, then I double it. After all, you need room for negotiating, right?
