It's good for girls to study finance, and the employment situation is ok. But, happiness, what is your happiness? For the same job, some people feel very happy, while others feel very bad. There is a bank next to my home. The girl at the counter works overtime until 9 pm every day, but the salary is high. She said that she had done enough and really didn't want to do it. Going to work every day is a living hell. She always wants to quit. But many of her friends envy her. What a good working environment, clean and beautiful lobby and high income.
So, happiness is up to you.
