Everyone is a salesperson because a significant portion of all professional life involves influencing and persuading others. The most critical sale an individual ever makes is selling themselves on their own potential for success and the value of their goals. To maintain this internal commitment, one must believe that their work or product genuinely helps others, rather than just focusing on financial gain. Individuals should actively seek social proof and feedback to reinforce their own belief in what they offer. By witnessing the positive impact of their efforts, professionals can overcome obstacles and avoid the trap of unselling themselves on their own ambitions.
