Beginning of this year I spoke to a colleague who, as the background on his phone (Thanks Mr. Novianto), had his personal mantra. I thought that was neat, so I made one for my desktop.
These are the three things I try to keep in mind as I go through work and life. Focus, Simplify, and Act. Then today, by chance, I stumble upon an article by Tony Robbins titled: The 3 Decisions That Will Change Your Financial Life. In the article he talks about the importance of Focusing, Figuring it out, and Doing something with it.
I think it's important to build yourself guidelines. Worth a quick read.
