A quick review about The LinkedIn Playbook by Adam Houlahan. The book is a short but thorough look at LinkedIn with some specific strategies that can be useful to grow your network and help you find more clients.
It's written more for the small business person looking to generate leads and business but even if you are looking to advance your career you'd find the tips useful.
Adam's emphasis on creating an impact is a good reminder of simple ways you can make your work more meaningful.

Every business goes through stages and each stage in each business needs a different strategy to flourish and prosper. I can teach you about the stages and the strategies to shortcut your success.
