Reputation is extremely important, but I also hear people saying that you shouldn’t be concerned about what others think about you. But dismissing reputation is not such a great idea. Your reputation ultimately determines your future opportunities, and successful people have always stressed that building and maintaining reputation is a fundamental ingredient to their success.
Building an attractive reputation is never about self-promotion, and a “sudden” breakthrough always comes after years of hard work, most of the time being a nerd. You could have bright business ideas or brilliant strategies, but success always lands in your reputation and takes years to build it. It sets the stage for interaction, builds trust, and it’s impossible to overestimate the value of it in your career or business.
