When considering a new market, first you should think about where your passion is. What hobbies or causes are you interested in where you can meet like-minded people? This way, your market is something you not only enjoy, but can provide you with ongoing potential business. Do you have an interest in a particular sport? Are you interested in a certain charitable cause? Is there an industry you are familiar with from a prior career?
After deciding on the market you want to penetrate, look for a mentor with experience in that market and ask for help. There are many successful advisors today looking to partner with the next generation of advisors and willing to form partnerships or mentor relationships.
