If one of your acquaintances knows any of your prospects, ask if you can use his or her name as a referral. Joining a professional association is a great way to make direct networking contact with knowledgeable people. Contact all of your referrals for appointments, regardless of their importance. All networking will not be productive, but remember, everybody you meet knows somebody important. What at first seems like an unproductive networking experience may end up producing a referral that leads to the opportunity of a lifetime.
Letters are good ice-breakers, but they are easily set aside.
Calls are great if you can get through the screening process. Whether you're defining or broadening your career options, emphasize that you are seeking ways in which you can utilize your skills more effectively. Agree to meet your contact at her or his convenience. You are responsible for what takes place in your meeting. Arrive prepared to talk briefly about your skills and accomplishments.
