I was sorry to hear of the death of Jackie Charlton.
I always remember a story he told about learning to be a football manager, because I think we can all learn from it.
In the first game and the first club he managed his team were losing at half time, so he started tearing a strip off them in the changing in the interval. After he finished ranting, a senior player looked up at him and said "Gov, you aren't helping." Charlton says that his was when he realized that by shouting and screaming he was only venting his own ego and embarrassment.
This he said was when he learned that the job was to make the best of what was available to him, and only ever to intervene with the positive intention of improving things.
Everyone can learn from that.
