Commercial real estate broker Hennessey (The Residential Agent’s Handbook for Commercial Real Estate) provides a smart if hodgepodge guide for readers looking to hone skills to better serve them in the modern economy. The author’s core principles are simple: be flexible, focus on service to others, and pursue new learning constantly. Hennessey also stresses the importance of understanding digital marketing, creating multiple income streams, becoming comfortable with public speaking, and perfecting the art of selling one’s skills. “Action items” (such as developing a reading habit, writing down criticisms from others for future analysis, establishing a meditation routine, and “committing to getting outside of your comfort zone”) offer specific advice based on each section’s lessons. The author also recommends outside resources to help readers create new skills, such as Toastmasters for those looking to refine their public speaking chops. In one of the most helpful sections, Hennessey asks readers to budget for the lifestyle they would like, then work backwards to figure out if their current city, home, job, and purchasing decisions can be altered to reach their goals. Hennessey’s empowering advice will give those struggling to keep up a firm foothold for moving forward. (Self-published)
