In good companies, though, information is shared. Make a point of sharing information you have with others around you regardless of company politics. Soon, people will learn that you are the source of good information and come to rely on you. Send out an email detailing innovations in your industry. Develop a newsletter that teaches people how to make better use of their computer.
