The day you convince yourself that you've mastered your craft or profession or even your relationships, is the day you cease to live. The thirst for knowledge and the mind's ravenous appetite for constant growth and evolution helps sustain a meaningful existence. If you cease to aim higher, you will surely fall short.
Backing up your argument with unnamed sources, rumored facts and hearsay only backs your view and your professional reputation into a corner. Argue the facts with validity, authority and substantial proof or walk away. It is ok to say you donβt know and it can serve your reputation better than sharing what you canβt prove.
