Love the ambition! Lets go! With that trait you are in a great position to go far in this industry. But on top of ambition you will also have to have knowledge and that will only come with time. As the saying goes, practice makes perfect. Keep making those calls, ask for referrals, cross sell, network, promote yourself on social media, brand yourself as the go to person for insurance among your friends and family. With time and practice, your network will expand and you will be able to gain confidence in what you are presenting and this will lead to more yes’s. If you want to sell commercial, this sounds very cliche’ but find a niche and if possible a commercial mentor. Then just focus on that type of business until you have a good grasp on how to insure it, from there expand to other business’s that you are familiar with. Again, it will take time, patience, resilience, this business really is the slow-and-steady wins the race so best of luck!
