Many ways to develop busienss as a lawyer

There is no one way to do business development.

It's OK if you are not outgoing. Find your quiet people.
It's OK if you start networking with your friends first. Ask them who else you should meet.
It's OK if you do not like big conferences or events. Do 1:1.
It's OK if you prefer virtual connections. Go nuts with meet+greets.
It's OK if you don't like to write or if you only want to write. Make it connect.
It's OK if you spoke at a conference and no work came from it immediately.
The "trick" is to find a business development approach that works for YOU!

Try the tactics that work for the rainmakers. Learn from them, listen to them. If their tactics work for you...great!

If their tactics didn't work... it doesn't mean you failed.
It means you try again.
It means you try something new. It means you keep going.
