Every year for the past 15 or so I have dedicated myself to learning some new topic. One year it was acupressure/reflexology. Another it was homeopathy. The years since I launched my own law firm the learning revolves around that, both substance and the practical/administrative aspect. This year I have dedicated two weeks of travel to attending conferences at Hillsdale College on the topics of Film Noir, The History of Christianity, and also attended one of their virtual courses on the Roman Republic.
I also took a two week course earlier this year to become a certified Family Law Mediator. I attended a Bench and Bar Conference and a Trusts and Estates Certification course.
We should never stop learning. Always be curious.
