I once had a law partner named Marvin who taught me what he called the “fish theory” of marketing. According to Marvin, marketing was simply a matter of throwing a fish back to every referral source who threw a fish to you. If you were referred a file from someone, you owed that person a file, and so it went.
New lawyers have a lot to learn about both the law, and how to practice law. Typically doing that will take up their entire workday, and then some.
I once had a partner named George. George had many very loyal clients, and I asked him to explain to me how he did it. This is one of the lessons which George taught me and which I integrated into my own philosophy about being an effective lawyer.
There is an easy way and a hard way to develop a good client base in the legal profession. The hard way is to work extremely long hours and be phenomenally good at what you do. I have met a few people who have done it this way, but not very many.
