Love is the Killer App by Tim Sanders is a solid read from 2002 with the subtitle How to Win Business and Influence Friends. The idea put forth by Sanders is to be what he calls a lovecat, someone who gives freely to others, and the book is organized into three sections: your knowledge, your network, and your compassion.
About your network, Sanders notes to keep track of your contacts, write down details about the people you interact with so that you remember. Collect relationships and then connect people with one another, follow up and make introductions.
About your compassion, Sanders quotes a definition of love as being the selfless promotion and growth of the other. He writes of the need to care, be human, and tell people things that matter which you may otherwise guard. Also highlighted is that compassion comes back; it refills those who give it.
Going back to the section on knowledge, Sanders notes to let reading be the thing that propels you, it doesn't require genius, and then you learn things, share them with your network, build out that network and help others. It's a good read from Sanders and some of the books he recommends are the following:
