You may also want to think about what you plan on doing with your free time once you begin working fewer hours per week at a job that most likely will not require your undivided intellectual and/or emotional attention 24 hours a day, 7 days a week. You need a hobby. Or a passion of some sort. Otherwise, you may end up falling back into law because you need to do something that the world recognizes as valuable, rather than what will bring you fulfillment or may actually be useful.
One thing I began doing when I left the law was reading more about personal finance and trying to come up with a financial plan for the future that would hopefully lead to a dignified retirement for me and my husband. I did not consider this a "hobby" at the time, but these days, when I am not working like a mad woman, I tend to be reading up on finance or listening to podcasts about it, or looking at spreadsheets documenting my journey out of student loan hell. I believe this now officially qualifies as a hobby.
What are some of the obstacles that have been holding you back from leaving the law?
