Cold calling is not for everybody. Going up to someone you don’t know and then trying to sell your services to them isn’t much better. Whenever you can, try to have a third party that knows both you and your prospect introduce the two of you. This third party can vouch for both of you, giving your prospect an immediate reason to trust you. Your contact, whether in person, on the phone, or online, will feel more relaxed talking to you, and thus will be more willing to listen to what you have to say. So, if you see someone you would like to reach out to, before you go and contact them on your own, try to find someone that both of you know to introduce the two of you. Social media can help you a lot here.
