I do something different nearly every single day.
A great day involves finishing up a project or a project milestone, and then sitting back knowing that I've created something that others can benefit from.

Start writing and get up in front of people. Writing and public speaking are a lot like playing a musical instrument: They require constant practice. Also, get to know why businesses and business leaders make the decisions they do. I had a few great mentors who were business leaders, and they helped me understand the world in ways I never suspected.
