Be authentic, transparent and most importantly, be who you are. Now, don’t confuse this with being confrontational or difficult for no apparent reason, what I actually refer to is sticking to your beliefs and opinions which are backed by facts, experience and values.
If you have seriously considered all options and alternatives and you have formed an educated opinion don’t change it simply because it may be unpopular at that point in time. Following the majority without thinking for yourself is definitely not the way one should live their professional or personal life.
