How did you choose which career path you wanted to take?

Wanted to get to know some people’s experiences and thoughts that made them and helped them become what they are today. Did you always want to be what you are today?
If not, what made you change direction?
Are you happy with what you are doing today? If not, where do you think life for you went wrong?

I know this is kinda a personal question, so I will deeply appreciate your answers. Thanks :)
