Take a minute to promote something another person is doing. Our "Social Media Crazy World" gives us plenty of opportunities to promote ourselves, but we can just as easily take the time to share a Tweet or Facebook Update on a project that is important to someone else (even when there is nothing to gain personally).
Do not make it all "Hey, Look At Me" --- Make some of it "Hey, Look At Them!!!"
The more you promote others, the more others will promote you. (Note... it often wont be the same people, as not everyone has it in them to shine the light on others.... it's okay.... promote them anyway!).
Have A Great Day.
