I spent many younger years as a sales rep getting paid on commission. Despite not caring for being in sales, I did quite well, and in hindsight I think it’s because what I didn’t have in charisma or Type-A chutzpah I made up for in genuine consultation. I really became an advocate of the client’s purchasing process, and they figured out that they could trust me to assist them in making a decision that suited their goals, not just mine.
During that time, one piece of advice I’d give seemed to resonate with folks:
“Either buy what you really want/need, or spend the least amount you can to get by.”
Lesson: you’ll otherwise end up wishing you had one more feature/benefit that would have cost you just a few more bucks, or you’ll find that you spent money on what you didn’t need. Avoid the lukewarm middle.
