a good leader first needs to have good intentions they need to have a purpose that will ensure that the people they are about to lead will do better with their leadership but of course good intention alone can not guarantee a good leader which is why education or knowledge is also important if you want to lead a country for example you’re gonna have to know about the laws your country upholds you should be able to represent your country among international grounds and you cannot do those with no proper education lastly and what i think is the most important the ability to listen is what makes a good leader
being experienced and an expert in the field will definitely help in leadership however time is ever changing some leaders are so bent on sticking with the old ways even if it’s not applicable to our new times anymore if you don’t know how to adapt to new environments experience will not help you be a good leader
Pretty much this.
I'd say, like many people here, that experience is the most important out of the three, then education and age. It takes more than this though.
The most important qualities is being good and strong willed, not falling for bribes, being ethical.
What does it mean good?
A good person is always ready to help others, isn't selfish, is kind to others, gentle when it's needed. Like a good parent that takes care of a child, spends time teaching it life and always being there to help and support. A bad parent will beat the child, abuse it, ignore its needs. Lack of ethics usually leads to mistakes that can be taken advantage of by people who want to make you their puppet.
