“A good leader is a person who takes a little more than his share of the blame and a little less than his share of the credit.”
If it is never your fault then you are not a leader. If you take all the credit, then you are not a leader.
I can’t think of anything that I have ever accomplished unilaterally and without help from someone else. What’s more, anything that has been accomplished has been made better because someone else contributed to the end product.
If you want to build trust you have to own it when things go wrong and give away the credit when things go right. Then people will trust you. Then you are a leader…
