Decide what type of lawyer you want to be.
If you are going to do door law ("whatever walks in the door"), you will be a failure. You will be running around town doing mildly competent work for little money. Be a master of a practice area, or two at the most.
 Keep your mouth shut.
If you now work for a firm, don't talk to anyone there. Not even that guy. Find your advice outside the firm. Far outside the firm.
 Don't buy shit.
"Shit" meaning garbage. There's plenty of resources out there that appear to be important. I recommend a shared office space arrangement for low or work-for rent rates, a computer, and business cards to start. Most other stuff turns out to be "shit."
 Read everything you can.
There are so many resources on-line. Here's the result of a quick Google search for "lawyer going solo."
 Stay out of the office.
If you want to do the mass mailing thing, great. Then you can stay in your office and take calls. If you are building a referral based business, every lunch you eat at your desk costs you money. If you don't understand that, I can't help you.
