6. Give back. My most important contacts professionally have been a result of my philanthropic work. I tend to join the marketing committees of non-profits I work with, and meet other people and collaborate on ideas. They get to see my skills firsthand and evaluate me as a colleague. You shouldn’t join an organization you’re not passionate about just to meet people, because that will backfire. But if you have an opportunity to partner your skills with a deserving organization, generating new business will be a nice result.
