From my experience speaking to founders, managers and business leaders, laying people off is one of the hardest things a person will have to do during their careers.
Being a good listener is one of the most important attributes you can have as an entrepreneur. You need to heed some (but definitely not all) of the advice given to you by advisors/mentors/investors, as well as take on feedback from your customers and users. It is also essential to listen to some of the ideas your team and employees come up with – if you don’t listen properly, you will regret it days/weeks/months down the line when things begin to unravel beneath your feet.
I have heard the phrase “knowledge is power” (“scientia potentia est” is the original phrase coined in Latin) regularly used throughout my life – at university, in the workplace and even in Hollywood movies. Never, though, have I felt this phrase to be more appropriate than when applied to behavioural & leadership psychology (or influencing people).
