There's a book on this: https://www.amazon.com/4-Hour-Workweek-Escape-Live-Anywhere/...

It's a best seller, people say it's life changing, but I have yet to hear of someone actually doing what's in the book. Even the author works extremely long hours after becoming an angel investor.

I would recommend reading the 4-hour workweek book from tim ferris. http://www.amazon.com/The-4-Hour-Workweek-Escape-Anywhere/dp...

Great advice for time management, works well for IT positions.
