Here are a couple more suggestions:

* Avoid being a roving coffee shop worker. 3 x $5 cups of coffee per day at three different places gets expensive (as in $4,050 per year). Just one coffee per business day is still $1,000 per year. That free Wifi isn't so free, now is it?

* Have meetings come to you when you can. Stop running to the Batmobile every time someone wants to talk.
