1. Your network is a far better source of jobs and opportunities than you can even imagine. The stronger the network, the faster the job search will yield results.
2. Have a diverse network. I had a large percentage of my network in a relatively small number of industries. When an industry lays off a large number of people across a lot of companies, that can make it more difficult than usual for your network to help out. Make and maintain connections in many locations and industries.
