Leader? Depends on what sort of leader you're referring to, doesn't it?
I don't fancy myself as a dictator. I wouldn't want my word to be treated above the word of all others. I wouldn't want to run a country, an empire or perhaps the entire planet by myself, with my rule. I wouldn't want that sort of power (nor should anyone) because not only is it too much, but because judgements can be wrong and humans are flawed.
I've seen that one man cannot rule over civilisation without making mistakes; we've all seen it. If I were in control of something as big as a country, I'd have a lot of people by my side, helping me make decisions and helping me learn from my mistakes. We all make mistakes; you've got to make mistakes if you're in control of a country. Would I relish the job? No, probably not. I've seen power corrupt people; corrupt my judgement. I'd be too paranoid of letting that happen to enjoy something like that.
But if we're talking about school projects here, then yes, make me the leader. As if I'd let any of my friends block my path of getting an A.
