Questions are vital
It's so easy for us to voice our opinion and jump to conclusions. But self control means probing and asking questions to understand better, before one gives their opinion, advice, counsel, evaluation or judgement regarding a person or situation.
Here is a thought from the book 'Good leaders ask great questions' by John Maxwell. The reason we ask questions is because before you attempt to set things right, make sure you see things. I hope this thought helps you as you work with office colleagues, team mates and clients.
