In whatever you do that matters to you, make sure to put a touch of your own unique personality.
When you apply for a job, when you write a blog post, when you deliver a speech, when you interact with others, when you are in a meeting, when you are bringing your boss up to speed, when you are out with your kids or talk to your parents. In every single situation there are many rules that have but one job: to make things predictable and dull.
Rules are important, and you should follow them. Few people are happy when all of their expectations are disregarded.
But remember to add a touch of your own unique personality. Few people are happy when all they see around is predictable and dull.
It is a difficult balance to strike. Just don’t forget who you are and what you stand for.
