Knowledge of the drivers of change in selling, the key success factors required in selling, the activities salespeople perform on the job, and the different kinds of selling jobs available go a long way toward helping a person make a decision if he or she might like to pursue selling as a career path. Successful salespeople always understand the roles that different individuals within the client company play in moving the relationship along, the buying decision process used by their clients, and how their clients go about making different types of purchases and how those differences impact salesperson’s approach to the client.
