Honestly I look past the little personality flaws because he's actually the best example for people in this world from the whole series in my opinion. He works hard for what he wants to achieve, sure he likes to talk which makes people view him as "cocky" but at the same time, he was no prodigy and had to work and train hard for anything he wanted to attain. He has goals, and he does everything he can to reach those goals no matter what! The sheer perseverance and will he has is in itself pure motivation, And for that I will always look up to him. When I was a kid watching Dragon Ball and Dragon Ball Z, Vegeta was the one I watched the most, from the anime world he taught me the most about how the world works. You want something, you have to work for it because no one gets ahead in life by waiting, being lazy or letting it fall into their lap... Personal reason why I'm such a huge Vegeta fan.
