In order to build a law practice that lasts—whether you do it at a huge firm or start your own–you have to find the intersection of your clients’ interests and your own.
This may seem like a no-brainer, but some would prescribe a different model:
This sort of law practice—the total separation of your own needs and your clients’—is neither sustainable nor honorable. If you spend all your time doing what your clients want, and none of it practicing law on your own terms, you will burn out in very short order. And your clients will not be very happy, either.
Instead, identify what you want out of your law practice, and figure out how to provide top-notch customer service while still practicing law on your own terms. That is the only way to a truly successful and sustainable law practice.
